Available On-Demand Precise Tracking with Indoor Location Systems Indoor location systems are transforming automotive manufacturing in two key areas: improving error-proofing and line-rebalancing on the production line, and identifying bottlenecks and improving efficiency on offline areas. The Skilled Labor Pool Evolves In an interview with Quality Magazine, manufacturing consulting company Advanced Technology Services’ President Jeff Owens speaks about the culprits behind—and remedies to—manufacturing’s shrinking skilled labor pool. When is a Subgroup Not a Subgroup? In some cases, what looks like a rational subgroup is emphatically not.

f you are to believe the news reports, quality is slipping. According to the J.D. Power and Associates 2011 U.S. Initial Quality Study (IQS), after an improvement in the quality of newly launched models every year from 2007 to 2010, the initial quality of 2011 new model launches has declined considerably. Overall initial quality improves to an average of 107 problems per 100 vehicles (PP100) in 2011 from 109 PP100 in 2010. However, the initial quality of launch models—those that are all-new or have had major redesigns—worsens by 10% to an average of 122 PP100 in 2011 from 111 PP100 in 2010. Conversely, carryover models—those that have had no significant redesign in the past year—have better initial quality than ever before. Owners of these vehicles report an average of just 103 PP100 in 2011, compared with 108 PP100 in 2010. “Exciting models with the latest features are crucial for winning over today’s demanding consumers,” says David Sargent, vice president of global vehicle research at J.D. Power and Associates. “However, automakers must not lose their focus on the importance of these models also achieving exceptional quality levels. Expected reliability continues to be the single most-important reason why new-vehicle buyers choose one model over another, and no manufacturer can afford to give consumers any doubts regarding the quality of their latest products.” The study notes that the decline in vehicle launch quality is evident in a number of areas, including the engine/ transmission and audio/entertainment/navigation categories. The two primary causes for this quality decline: • As automakers are designing engine and transmission software to meet government regulations and make their models as economical as possible, this sometimes leads to the engine or transmission

“hesitating” when accelerating or changing gears. Consumers this year are reporting this as a problem more often than in past years. • Automakers are accelerating the introduction of multimedia technology into their models, including hands-free and voice-activation systems. Many consumers want this technology, which is perceived to enhance convenience and safety, but some vehicle owners report that their system is not intuitive and/ or does not always function properly. It strikes me that the ease of use of an item and its functioning properly are lumped into the same category. A system that is not intuitive doesn’t mean it is of poor quality. To my knowledge, no one I know has ever suffered more than a paper cut reading an owner’s manual. Besides, what is intuitive to me isn't necessarily intuitive to you. I receive myriad press releases every week on new equipment and software that the manufacturer labels as “intuitive” and “user friendly.” Certainly not all of the systems and software can be used right out of the box, but does that mean they are low–quality products? Certainly not. Should ease of use and quality be lumped into the same category?

INITIAL QUALITY OF RECENT VEHICLE LAUNCHES DECLINES WESTLAKE VILLAGE, CA—After an improvement in the quality of newly launched models every year from 2007 to 2010, the initial quality of 2011 new model launches has declined considerably, according to the J.D. Power and Associates 2011 U.S. Initial Quality Study (IQS). The study has been conducted annually for the past 25 years. Overall initial quality improves to an average of 107 problems per 100 vehicles (PP100) in 2011 from 109 PP100 in 2010. However, the initial quality of launch models—those that are all-new or have had major redesigns—worsens by 10% to an average of 122 PP100 in 2011 from 111 PP100 in 2010. Conversely, carryover models—those that have had no significant redesign in the past year—have better initial quality than ever before. Owners of these vehicles report an average of just 103 PP100 in 2011, compared with 108 PP100 in 2010. Lower PP100 scores indicate a lower rate of problem incidences and therefore higher initial quality. “Exciting models with the latest features are crucial for winning over today’s demanding consumers,” says David Sargent, vice president of global vehicle research at J.D. Power and Associates. “However, automakers must not lose their focus on the importance of these models also achieving exceptional quality levels. Expected reliability continues to be the single-most-important reason why new-vehicle buyers choose one model over another, and no manufacturer can afford to give consumers any doubts regarding the quality of their latest products.” Only seven all-new or redesigned models rank among the top three of their respective award segments, com-

pared with 17 models in 2010, and only one launch model receives a segment award this year vs. five launch models in 2010. Just one-fourth of redesigned models perform better than the outgoing previous-generation model did in 2010, and eight all-new models perform above their respective award segment average. The decline in vehicle launch quality is evident in a number of areas, most notably the engine/transmission and audio/entertainment/navigation categories. There are two primary causes for this quality decline: • With high fuel prices and more stringent government regulations, automakers are designing engine and transmission software to make their models as economical as possible. However, this sometimes leads to the engine or transmission “hesitating” when accelerating or changing gears, and consumers this year are reporting this as a problem more often than in past years. • Automakers also are accelerating the introduction of multimedia technology into their models, including hands-free and voice-activation systems. Many consumers are attracted by this type of technology, which is perceived to enhance convenience and safety, but some vehicle owners report that their system is not intuitive and/ or does not always function properly. “Clearly, consumers are interested in having new technology in their vehicles, but automakers must ensure that the technology is ready for prime time,” says Sargent. “Successful companies will be those that can take this incredibly complex technology and make it reliable, seamless and easy for owners to operate while they are driving. There is an understandable desire to bring these technologies to

market quickly, but automakers must be careful to walk before they run.” While overall vehicle quality continues to improve, the introduction of new technology is expected to continue to pose challenges for automakers. Overall problem rates for audio/entertainment/navigation systems in 2011 are 18% higher than in 2010 and 28% higher than in 2009. The Initial Quality Study serves as the industry benchmark for newvehicle quality measured at 90 days of ownership. The study is used extensively by manufacturers worldwide to help them design and build better vehicles and by consumers to help them in their vehicle purchase decisions. Initial quality has been shown throughout the years to be an excellent predictor of long-term durability, which directly impacts consumer purchase decisions. The study captures problems experienced by owners in two distinct categories: design-related problems and defects and malfunctions. Lexus leads the overall nameplate rankings with 73 PP100 on average.

Following in the rankings are Honda (which improves to second rank position in 2011 from sixth in 2010), Acura, Mercedes-Benz and Mazda (which improves to fifth rank position in 2011 from 18th in 2010), respectively. Land Rover posts the largest improvement in 2011, reducing problems by 47 PP100 from 2010. Honda garners seven segment awards for the Accord, Accord Crosstour, Civic (in a tie), Element, Fit, Insight (in a tie) and Ridgeline. Lexus receives four segment awards for the ES, GS, GX and LS models. For a second consecutive year, the Lexus LS has the fewest quality problems in the industry with just 54 PP100. Chevrolet, Ford and Mercedes-Benz receive two awards each. Chevrolet receives awards for the HHR and the Tahoe; Ford for the F-150 and the Taurus; and Mercedes-Benz for the GLKClass and the E-Class cabriolet/coupe. Also receiving segment awards are the Cadillac Escalade; Chrysler Town & Country; Dodge Challenger; and Mazda MX-5 Miata.

NEWS Among all-new and redesigned models, the Hyundai Equus and Dodge Durango are notably strong performers, each ranking second in their respective segment. The 2011 U.S. Initial Quality Study is based on responses from more than 73,000 purchasers and lessees of new 2011 model-year cars, trucks and multiactivity vehicles surveyed after 90 days of ownership. The study is based on a 228-question battery designed to provide manufacturers with information to facilitate identifying problems and drive product improvement. The study was fielded between February and May 2011.

WHITE HOUSE INITIATIVES ADDRESS LACK OF SKILLED MANUFACTURING LABOR CLEVELAND—The National Tooling and Machining Association (NTMA) and the Precision Metalforming Association (PMA) salute a White House initiative to expand U.S. manufacturing by recruiting and educating more skilled workers. The initiative mirrors ongoing efforts by NTMA, PMA and other manufacturing groups to develop more qualified workers for the metalforming, tooling and machining industries through two main avenues: actively recruiting new workers and developing widely recognized credentials that signal their qualifications. “It is essential to the future of our industry that we find creative ways to attract the attention of new workers,” says NTMA President Dave Tilstone. “That’s why NTMA sponsors activities like the National Robotics League, which draws students to technical careers by partnering student teams with local manufacturers to build complex machines designed to do battle

and test ingenuity—all while building high-tech skills.” PMA President Bill Gaskin says that alongside creative recruitment efforts, the key to developing more skilled workers in the United States is the use of uniform, widely-recognized and industry-driven credentials to demonstrate competency in the specific industry skills needed by employers. “PMA and NTMA have worked closely with the National Association of Manufacturers to devise a way to validate metalworking industry skills through the National Institute of Metalworking Skills (NIMS) machining and metalforming certifications,” Gaskin notes. “NIMS certifications offer a concrete path for students to acquire or increase specific skills, while in turn providing a set of credentials that signal employers that they’re able to perform to quality standards in a skilled machining or metalworking job. Both the worker and employer benefit as a result.”

MEXICO’S MANUFACTURING CONTINUES TO GROW MEXICO CITY—Manufacturing in Mexico continues to grow in 2011 with both new and existing companies expanding operations across various sectors, most notably record-breaking numbers in auto production and vehicle exports. In May, more than 213,000 cars were manufactured in the country, 19.4% more than in the same period in 2010, representing the highest record, according to Eduardo Solis, president of the Mexican Association of the Automotive Industry (AMIA). In the same month, exports rose 21.3%. May capped a fivemonth growth period for the first part of 2011, increasing 17.1% over 2010 figures and 16.4% over 2008 rates. In

addition, Mexico, as the ninth-biggest vehicle producer in the world, produced a record 2.261 million vehicles in 2010, up 50% from 2009, according to AMIA. Continuing the trend in increased vehicle production, Mazda announced that it will begin construction of a new plant in Guanajuato, Mexico, this fall, with vehicle production to start in the second half of 2013. The investment of $500 million will allow Mazda to produce at least 50,000 cars a year at the plant. In addition, the Daimler Trucks North America plant in Saltillo, Mexico, is including a third shift, adding 479 more manufacturing workers and 32 additional staff workers. This will help meet demand for Daimler Trucks North America’s its Freightliner and Western Star trucks. Carlos Guzman, ProMexico’s CEO, recently stated that “because of its manufacturing capacity, Mexico is a very competitive platform for several European and Asian economies that are looking to penetrate or increase their participation in the United States. Mexico is a remarkable manufacturing hub for the automotive industry, among others.” Automotive parts supplier Delphi is investing $11 million and generating 2,000 jobs for a new auto parts manufacturing facility in the state of Durango. This will be the first Delphi plant in that state. Additional manufacturing growth is illustrated by Hawker Beechcraft’s continued expansion in Chihuahua City. The company has opened two plants in the city in 2011, with plans to invest $108 million more in opening another new plant, which will create 600 new jobs assembling structural parts for King Air turboprop airplanes. In addition to auto and aircraft production, the steel industry also is

growing in Mexico. President Felipe Calderon announced in June that Posco, a Korea-based company, is going to expand its steel plant in Altamira, Tamaulipas, with an investment of $300 million. According to the president, this expansion will create 300 direct jobs and more than 600 indirect positions. During the Posco expansion announcement event, Egidio Torre, Tamaulipas Governor, said that this investment shows that there is confidence to invest in the state. With such expansion continuing throughout Mexico, and in light of Mazda’s most recent announcement, Calderon promises that Mexico will continue to work to promote more investment in the automotive, aerospace, electronic and manufacturing sectors. This will continue to strengthen the country’s worldwide reputation and position as an international manufacturing leader.

MANUFACTURING CONFIDENCE IN U.S. ECONOMY DROPS CHICAGO–U.S. manufacturing leaders have turned pessimistic regarding the U.S. economy, according to Grant Thornton LLP’s most recent Business Optimism Index, a quarterly survey of U.S. manufacturing business leaders. Only 40% believe the U.S. economy will improve in the next six months, down from 60% three months earlier. At the same time, 26% believe the U.S. economy will get worse, up from 3%. “There are many factors causing concern amongst U.S. manufacturing leaders,” says Wally Gruenes, manufacturing practice leader at Grant Thornton LLP. “Soaring energy and raw material costs and Japanese manufacturing supply chain disruptions are weighing heavily, as are unresolved U.S. debt reduction issues and a corporate tax rate that still puts the United States at a global competitive disadvantage.”

SANTA MONICA, CA—Sales of hybrid and plug-in electric vehicles fell to a 16-month low in May, dragged down by real and imagined supply constraints and increased competition from lowerpriced gas-powered small cars, reports Edmunds’ AutoObserver.com. May sales of hybrid and electric-drive vehicles were off 35.8% from a year earlier, lead by dramatic declines in sales of Toyota and Honda models. Overall, Toyota and Lexus hybrids dropped 45.1% for the month. Honda, the second-largest producer of hybrids, saw its sales in the segment fall 29% in May. “For those selling hybrids, it is incredibly bad luck that the Japanese earthquake and associated production disruptions occurred as gas prices were reaching their highest levels in three

years,” says Edmunds.com Chief Economist Lacey Plache. “While Japanese automakers may well gain back their lost share on other vehicles, hybrids will face an even steeper climb back to previous levels, given the greater and growing competition from fuelefficient, nonhybrid vehicles.” Leading the slump was the decline in Toyota Prius sales, which traditionally accounts for about half of the hybrid market. A total of 6,924 Priuses were sold in May, down 51% from the same month last year. Low supply and higher prices have made the popular hybrid less palatable to consumers. A pricing analysis by Edmunds.com found that the effective cost of a new Prius was $2,500 more in May than just three months ago.

NEW ANALYSIS ON BEST PLACES FOR MANUFACTURERS GREAT BARRINGTON, MA—Despite the conventional wisdom that the South is best place for manufacturing in the United States, eight of the top 10 states for cost-efficient manufacturing are located in the West and Northeast, according to new research by the American Institute for Economic Research (AIER). The research is discussed in the new AIER Economic Bulletin “Competitiveness and Business Costs.” AIER Research Fellow Lei Chen, Ph.D., says the “findings explain why manufacturing firms still may want to consider locating their businesses in the Northeast and on the West coast.” Using 2007 economic census data and a completely data-driven analysis method known as data envelopment analysis, Chen found that the most cost-efficient manufacturing took place in Oregon, Connecticut, Iowa, North Carolina, New York, Arizona, Massachusetts, Nevada, Colorado and Washington. His analysis examined, from an efficiency perspective, inputs including production labor, non-production labor, capital, energy and materials. The 10 states with the least cost-efficient manufacturing, his analysis showed, were Mississippi, North Dakota, Kentucky, Vermont, Alabama, Louisiana, Alaska, Montana, South Carolina and Idaho. “States that are the most costefficient have manufacturing bases that allocate their resources in such a way that relatively low cost inputs replace high cost ones and inputs are used in

the most productive manner,” says Chen. “If all manufacturers allocated their resources this way, on average, U.S. manufacturers could reduce their total production costs by 15.6 % and still produce the same quantities of output.” Chen’s findings are consistent with those of an earlier study, also revealed in AIER’s Economic Bulletin. The earlier study, which Chen participated in while still on the UConn faculty, provides a state-by-state comparison of the production cost per dollar output of manufactured goods—that is, how much it cost to produce one dollar value of goods in different states. That study identified Oregon as the state with the lowest unit production cost per dollar of output. Oregon was followed by North Carolina, Virginia, Arizona and New York. Wyoming, New Mexico, Connecticut, Missouri and South Dakota rounded out the top 10. The bottom 10, the states with the highest unit manufacturing cost per dollar output, included Vermont, New Hampshire, Rhode Island, West Virginia, Idaho, Nebraska, Alaska, Michigan, South Carolina and Kentucky. Arkansas, Louisiana, Mississippi, Tennessee and Alabama—all of which have become popular manufacturing hubs in recent years—all had costs in excess of the national average of 83.3 cents per dollar output.

FACE OF QUALITY

FIVE KEY STRATEGIES TO ENHANCE

QUALITY CULTURE USE YOUR STRENGTH AND LEADERSHIP TO REMAIN ECONOMICALLY HEALTHY. Editor’s note: This is part two of a two-part series on enhancing quality culture.

O

rganizations should focus on some key quality process areas to meet the demands of the competitive environment and maintain their quality competitiveness.

JIM L. SMITH

1. Develop a new strategic and operational leadership model of quality. It has become increasingly clear that organizations that survive and do well in the markets approach quality as a key part of their strategy. Senior management, in these organizations, has become more hands-on in quality-related activities just as they do in other areas such as finance. This attention provides leadership and a clearly defined role for the quality professional, as well as sending a powerful message across the organization. A key concept that organizations need to adopt is that there is no such thing as a quality problem. When thinking of quality problems, organizations look to the quality manager or the quality department for solutions or where to place the blame. In truth, the problems that exist include: design problems; manufacturing problems; and manufacturing engineering problems. 2. Develop and launch new products which will provide consistent customer value. Faster launches of high quality products rely on strong management leadership, technology and focused quality systems. This integration leads to shorter cycle times with complete quality disciplines to ensure successful product launches delivering consistent customer value performance. For some, this is quite different from the past. While well intentioned and well constructed, some processes were separate islands without bridges to integrate activities with other processes across the organization. In today’s environment, it is imperative that we shift toward more carefully structured, quality-driven activities that pay close attention to customer value practices designed to meet the needs and expectations of the market. Measurement practices need to be in place to ensure the organization is on target and to avoid the backward creep of product quality. 3. Foster a more consistent motivation of human resources to support quality initiatives. This is a departure from the earlier management practice of putting on well-packaged motivational sessions or

speeches. While often entertaining, these were mostly shallow because when employees went back to work, feeling euphoric, they typically faced ambiguous quality practices and a business as usual atmosphere. Departmental walls remained up which ensured quality improvement remained slow and mostly ineffective in making real change. Today’s environment demands a workplace beyond the worker empowerment of the past. The emphasis needs to be on creating an environment of openness and integrity, of which respect, trust and honesty are cornerstones. This encourages the development of individual quality improvement entrepreneurs. Those best qualified to establish a better way are the ones closest to the actual work. When they are given the ability, tools and support, they also are the ones who can implement the changes. 4. Effective management of suppliers and purchasing activities. In quality-focused organizations this activity is governed by strong, systematic management and emphasis on the quality of suppliers. These organizations focus heavily on better communications within their organizations and strive for a more productive, long-term partnership with its suppliers. This is different than in the past where a “negotiate them down” and combative approach drew battle lines between the entities. 5. Understand the economics of quality. Organizations can do well by fully understanding their total cost of nonquality as it relates to the failure to achieve what Dr. A.V. Feigenbaum called “customer value satisfaction.” I had the opportunity to visit a small company that had a strong quality improvement program focused only on driving down their cost of poor quality. They had everyone involved and accomplished wonderful results through understanding their true cost of failure and their quest to do it right the first time. Organizations have continued to improve, but the lessons have been hard. It’s not only the organizational leadership who needs to change, but the quality professionals and other members of the organization. It is up to us, but remember, you don’t have to do any of these things—survival is not compulsory. Jim L.

T

he digital display has become so much a part of our life, I wonder what the world would do without it. First it was watches. Everyone had to have a digital model even though you can get a faster indication of the time with a fleeting glance at an analog model because you actually have to read and process the numbers on a digital display. What’s in is not necesHILL COX sarily what’s best. Metrology is one of many fields that has felt the impact of digital displays and measuring systems—for better or worse. Anyone can use an instrument and get a reading up on the display. Unfortunately, too many people assume that reading is correct because they’ve never been taught the basics of measurement. It wasn’t that long ago that people worked their way up in a manufacturing company after serving time in various related departments along the way. When they had the opportunity The result to go into the inspection department, they had [of inexperience] is a group a pretty good groundof people who are instrument ing in the basics and an readers but have no idea what appreciation of what a ten-thousandth of an the numbers mean. inch or a micron meant in practical terms. They also had experience in knowing where some manufacturing processes could go off the rails dimensionally, and knew what to look for to prevent such things coming at them out of the blue. That background and training rarely seems to happen much any more. Today, the emphasis is on whether or not the person is computer savvy, rather than skilled or experienced in measurement. The result is a group of people who are instrument readers but have no idea what the numbers mean. In a worst case scenario, they are essentially data collectors, pushing buttons to send data to a software package in a central computer. The result of all of this is a dazzling display of pretty charts and printouts that indicate everything is okay—but sometimes it’s not. We often see examples of digital blindness when customers get a calibration report that indicates something may not be right, but it goes straight into the files so they can prove they had the item calibrated. The piece of paper is more important than what is on it.

QUALITY | August 2011

Of course, there are some quality auditors out there who do not suffer from digital blindness and actually look at the reports and understand what the digits mean. And then they start asking those embarrassing questions. In a reversal of this situation, we have folks that question why this year’s report on their gage blocks differs from the one issued last year by a millionth or two here and there. They’re not blind; they see the digits but just don’t know what they mean. In such cases the report is questioned because the blocks have rarely been used and only by a heavenly entity so the changes couldn’t be the result of wear, or so it is claimed. Discussions of measurement uncertainty and block stability will go nowhere. Adding a couple of digits to a digital display is done relatively cheaply and is one of the curses of the technology. Too often the improved resolution is meaningless but it does help to sell instruments, irrespective of how good or bad they are from an accuracy point of view. When you get down to the last digit, metrology knowledge will overcome digital blindness. But getting it is not easy in today’s workplace. This is particularly so when folks believe that massaging numbers with computer programs will keep everything on the straight and narrow. Long forgotten is the old rule, garbage in-garbage out, which means if you don’t know your metrology, you could be loading up an impressive data bank based on dicey measurements. What’s the answer? Training is the obvious answer, but training comes in many forms. For many companies, showing employees how to use the equipment is the gold standard. Unfortunately, this type of training doesn’t answer the “What went wrong?” question when things come unstuck. “I dunno...” will be the usual answer. Someone with some good training will be able to point to a couple of areas, but more likely than not, they’ll sense something not being right before the digits trigger panic stations in the quality department. In the absence of training, the only advice I can offer for everyone involved in the process is never believe the last digit. Hill Cox president of Frank J. Cox Sales Ltd.

TORQUE TOOL TESTING:

A PRIMER Learn the foundation for good torque testing. BY GREG KATSIS

T

orque equals force times distance. This equation sets the foundation for all torque calibration—that of the torque testers as well as the tools. It also sets the starting point for torque testing; the weights (force) and arms (distance) used to calibrate the tester must themselves be certified as accurate to national standards. It is strongly urged that these components be calibrated and certified only by calibration laboratories having ISO 17025 accreditation and an applicable scope. If you test torque tools but send your tester out for calibration, the tester is the foundation of the calibration system. To ensure that the foundation is solid, the calibration laboratory performing the service should have ISO 17025 accreditation for torque tester calibration. The laboratory must have a scope that includes a torque range encompassing that of the tester.

STANDARDS The ASME B107.300-2010 standard and the ISO 6789 standard supply important information on torque tools and the testers required to test and calibrate them. These standards form an excellent starting point for anyone involved in testing torque tools. FREQUENCY “How often should we test the tools?” is among the most frequently asked questions of every torque tool manufacturer. It also is one of the most frequent sources of misunderstanding and problems. The questioner usually hopes for a simple answer, and the simplest answer is a fixed calendar-based interval. Unfortunately, a fixed calendar interval ignores a host of factors that affect the time when calibration is needed. Is the tool brand new or does it have 300,000 cycles (uses) on it? Is it used to tighten 10 fasteners

each day or 1,200? Is the daily usage rate constant, increasing or decreasing? Is it being used at 40% of capacity or 98%? Are we talking about one type of torque tool or several? Are these all of the same make and model or are there different designs from different manufacturers? These questions apply to each tool individually, and the answer is likely to be different from tool to tool. Applying a simple calendar answer to a population of torque tools invites both interval error types—too frequent and too infrequent calibration. The overly simple approach can even result in the creation of both errors simultaneously. This results in money spent for excessive calibration of some tools while not calibrating others in time to prevent assembly problems. The Calibration Interval Committee of NCSL International faced and addressed this issue some time ago. Their RP-1 (Recommended Practice) publication addressing calibration intervals gives not one, but multiple ways in which a reliable calibration interval can be calculated and maintained through the life of the measurement instrument (the torque tool and the torque tester). Better still, these methods are for the most part easy to understand and cost virtually nothing to implement. The data-driven methods for calibration interval determination effectively adjust for changes in tool (or tester) usage rates, age and wear. The methods in this RP are proven and provide objective answers that reduce the probability of over- and under-calibration. Over time they provide a solid view of the stability (and ownership cost) of each torque tool. This data should be used to make future tool purchases on a more objective basis. EQUIPMENT The advent of the digital torque tester changed the landscape of torque tool calibration. The mechanical torque testers of just a couple of decades ago were cumbersome objects, heavily reliant on the individual to interpolate from

a dial and to manually record results. Current-generation digital testers are easy to set up and use, require no interpolation and communicate with computers seamlessly. When selecting a torque tester, the accuracy of the tester in relationship to the accuracy of the tools is a primary factor. The tester must be at least four times as accurate as the tools to be tested with it. The ±1% I.V. tester that is acceptable for testing clicker-type torque wrenches is not sufficiently accurate for testing most dial (±3%), flat beam (±2%) or digital (±1%) tools. Further, the tester must support test modes and torque ranges that accommodate the types and capacities of the tools to be tested. Mechanical loaders can be significant assets in ensuring the quality of the test results and the productivity of the technician performing the calibrations. A well-designed mechanical loader will apply force to the tool through a single point of contact, and remain perpendicular to the tool, throughout the arc of movement. Some loaders use a moving arm to achieve these requirements, while others hold the tool in a fixed position and rotate the torque transducer. Either method can work since both can accommodate the fixed distance and perpendicularity requirements. The best designs also will reduce technician fatigue, thus helping maintain technician productivity throughout the day.

Earlier-generation torque testers were reasonably accurate, but were large and cumbersome, usually requiring interpolation to obtain a torque value. Source: Sturtevant Richmont

When a tester and mechanical loader are coupled with purpose-designed software, the calibration process can be made more error-proof and more efficient. Optimal test quality and productivity is attained when the software stores the test protocol, downloads it to and controls the tester during the testing, and uploads each result as it is obtained. Software that also stores the results and outputs a certificate of calibration meeting all requirements on demand will make the process highly cost effective. If power tools are to be tested, additional considerations must be accommodated. Automatic and manual shutoff tools are slightly different in their behaviors, as are electric and pneumatic tools. Additional equipment such as rundown fixtures may be needed to obtain accurate results, and the tester itself must have filters that cover the tool types, brands and designs to be tested. ISO 5393 can be of assistance in determining what is necessary to fill any given set of needs in the testing of power tools. A well-designed mechanical loader will apply force to the tool through a single point of contact, and remain perpendicular to the tool, throughout the arc of movement. It also will ensure that the tool remains perpendicular to the transducer during loading.

aspect of the sensor’s calibrated light source. By customizing the quantity, density and orientation of the sensor’s laser lines through a simple user interface, image acquisition is optimized on a feature by feature basis. The operator can configure tightly spaced laser lines for small, complex features, increase the number of laser lines to robustly measure challenging materials and alter the orientation of the laser lines to accommodate the differences between multiple parts manufactured on the same assembly line. Prior to Helix, manufacturers were forced to purchase and deploy multiple measurement technologies in order to implement a comprehensive quality strategy. Intelligent Illumination serves as the foundation of a single, in-process solution capable of precisely measuring key dimensional features, as well as generating full 3-D point clouds–allowing, for the first time, a truly integrated, 3-D metrology solution. Harry Rittenour, Perceptron’s president and CEO, states, “Our Helix solution is the most significant development in sensor technology in the past 15 years, and represents a quantum leap in 3-D metrology. Nothing comparable exists in the market today. Helix will provide our customers with a powerful tool for overcoming the challenges they face on a daily basis and a means to successfully implement their most farreaching and innovative strategies for the future.” The benefits of Enhanced Measurement Volume is simple—reduce the amount of hardware and move back to fixed sensors, saving cost and time. Helix sensors use increased measurement volumes, in many cases more than 100 times that of competitive offerings, to effectively and efficiently support those f lexible manufacturing processes. By using Helix solutions, Perceptron’s customers can measure more features on multiple models with fewer sensors, simultaneously adding value and saving money.

History of

Hardness Testing Hardness testing plays an important role in materials testing, quality control and acceptance of components. BY BILL O’NEILL

H

ardness, as applied to most materials, and in particular metals, is a valuable, revealing and commonly employed mechanical test that has been in use in various forms for more than 250 years. Certainly, as a material property, its value and importance cannot be understated. The information from a hardness test can complement and often be used in conjunction with other material verification techniques such as tensile or compression to provide critical performance information. How important and useful is material and hardness testing? Consider the information provided and its significance in structural, aerospace, automotive, quality control, failure analysis and many other forms of manufacturing and industry. Determining these material properties provides valuable insight to the durability, strength, flexibility and capabilities of a variety of component types from raw materials to prepared specimens and finished goods.

QUALITY | August 2011

Over the years, various methods for determining the hardness of materials have been developed and employed at varying levels of success. From early forms of scratch testing to sophisticated automated imaging, hardness testing has evolved into an efficient, accurate and valued material test method. SCRATCH TESTING While testing techniques and hardware has significantly improved, particularly in recent years and in step with rapidly advancing electronics, computer, hardware and programming capabilities, earlier, basic forms of hardness testing, such as the simple scratch test, sufficed for the need of the relevant era. Some of the earliest forms of bar scratch testing date back to about 1722. These tests were based on a bar that increased in hardness from end to end. The level at which the material being tested could form a scratch on the bar was a determining factor in the specimens hardness.

Later, in 1822, hardness testing forms were introduced that d th ha included scratching material surfaces with a diamond and measuring the width of the resultant line, a test eventually known as the Mohs scale. In some processes this method is still utilized today. The Mohs scale consists of 10 minerals, ordered from hardest at 10 (diamond) to softest at 1 (talc). Each mineral can scratch those that fall below it in the scale hierarchy. The Mohs scale is not linear; the difference in hardness between 9 and 10 is significantly more than that between 1 and 2. To put the Mohs scale into perspective, a tangible example is that of hardened tool steel which falls at approximately 7 or 8 on the scale. During the next 75 years, other more refined versions of the scratch test were introduced including integrated microscope, stage and diamond apparatuses that applied increasing loads up to 3 grams. The material to be tested was scratched under load variants and then compared to a standard set of scratches of known value. A more sophisticated version of this system employed a diamond mounted at the end of a tapered steel spring.

The other end of the spring was connected to a balance arm with a 3 gram weight. The material being tested was moved by a hand-actuated wheel and worm gear system, on top of which sat a stage and holding fixture for the material. A fixed pressure was applied as the material was traversed, resulting in a “cut” in the material which was then measured under the microscope with the aid of filar micrometer eyepiece. A mathematical formula, inherent to the process, was then used to derive the hardness. INDENTION TESTS Later, indentation type hardness was introduced. One early form developed about 1859, was based on the load required to produce a 3.5 millimeter indent in the material. The depth was measured with a vernier scale system and the total load needed to reach the 3.5 millimeter was called the hardness. The penetrator consisted of a truncated cone that tapered from 5 millimeter at the top to 1.25 millimeter at the point. This method was mostly effective in soft materials. Another early form of indentation test involved pressing right angles geometries of the same test material into one another and measuring the width of the resulting impression. Various formats evolved from this technique during the early 1900s that likewise used “mutual” indentation of cylindrical test material with the longitudinal axis pressed at right angles to each other. The first widely accepted and standardized indentation-hardness test was proposed by J. A. Brinell in 1900. Brinell’s interest in materials science grew during his involvement in a several Swedish iron companies and his desire to have a consistent and fast means of determining material hardness. The Brinell hardness test, still widely used today, consists of indenting the metal surface with a 1 to 10 millimeter diameter steel or, most recently, a tungsten carbide ball at heavy loads of up to 3,000 kilograms. The resultant impression, the diameter of the indentation, is measured with a low-power microscope after removal of the load. The average of two readings of the diameter of the impression at right angles are made and mathematically calculated to a

hardness value. The Brinell test essentially introduced the production phase of indentation hardness testing and opened the way for additional indentation tests that were more relevant to material types. Around the same time as the Brinell was developing as a useful test the Scleroscope hardness tester was introduced as one of the first “nonmarking” hardness-testing instruments.

Albert F. Shore, who founded the Shore Instrument Manufacturing Co. in New York, and whose name is now synonymous with durometer testing, engineered the Scleroscope as an alternative hardness test. The Scleroscope used a diamond tipped “hammer,” held within a glassfronted tube that fell, from a height of 10 inches, onto a test specimen. The rebound of the hammer was mea-

MORE EFFICIENT TESTING NEEDS As the 20th century progressed and endured two world wars, with the simultaneous blossoming of the industrial revolution, increased manufacturing requirements and global industrialization brought an urgent demand for more refined and efficient test methods and new techniques began to develop. Accurate, efficient forms of testing were needed in reaction to heavy manufacturing demands, structural failures and the need to design sufficient material integrity into the growing global infrastructure. As an alternative to the Brinell, the Vickers hardness test was developed in 1924 by two gentlemen, Smith and Sandland, at Vickers Ltd., a British engineering conglomerate. The test was designed in reaction to the need to have a more refined test over the material limitations than the Brinell was effective on. The Vickers test uses the same principle as the Brinell, that of a regulated impression on the material, but instead utilized a pyramid shaped diamond rather than the Brinell ball indenter.

This resulted in a more consistent and versatile hardness test. Later, in 1939, an alternative to the Vickers test was introduced by Fredrick Knoop at the U.S. National Bureau of Standards. The Knoop test utilized a shallower, elongated format of the diamond pyramid and was designed for use under lower test forces than the Vickers hardness test, allowing for more accurate testing of brittle or thin materials. Both the Vickers and Knoop tests continue as popular hardness analysis methods today. Although conceived as an idea in 1908 by a Viennese professor, Paul Ludwik, the Rockwell indentation test did not become of commercial importance until around 1914 when brothers Stanley and Hugh Rockwell, working from a manufacturing company in Bristol, CT, expanded on the idea of utilizing a conical diamond indention test based on displacement and applied for a patent for a Rockwell tester design. The principal criterion for this tester was to provide a quick method for determining the effects of heat treatment on steel bearing races.

One of the main strengths of the Rockwell was the small area of indentation needed. It also is much easier to use as readings are direct, without the need for calculations or secondary measurements. The patent application was approved on February 11, 1919, and later, in 1924 an improved design patent was granted. Simultaneously, Stanley Rockwell was starting commercial production of Rockwell testers in collaboration with instrument manufacturer Charles H. Wilson in Hartford, CT. The company grew into the Wilson Mechanical Instrument Co. and became known as the premium producer of Rockwell testers. After some ownership changes through the latter 1900s, Wilson was acquired in 1993 by Instron and today has become an integral part of Instron/ Illinois Tool Works. Now known as Wilson Hardness, the combined expertise of Instron/Wilson, coupled with the subsequent acquisitions of Wolpert Hardness and Reicherter Hardness, have led to the engineering and production of cutting edge hardness systems.

50 YEARS OF QUALITY remains as one of the most efficient and widely used hardness test types in use. Hardness testing technology remained fairly consistent throughout the mid to latter 1900s, most systems typically utilizing the dead weight method of applying the test forces. While the deadweight technique is fairly simple, reliable and was widely accepted, the method is not without some ambiguities. Labor-intensive production, coupled with the complexities involved in a highly mechanical system depending on levers, pivots and guides led the need for further development and it became evident that other newly developed forms of force regulation used in measurement instrumentation could be applied to hardness testing as well. CLOSED LOOP SYSTEMS With increasing demands for productivity, accuracy, user features and repeatability, closed-loop, load cell technology became a factor in hardness testing. During the 1950s, Instron pioneered the use of closed loop systems on tensile testing instruments.

Closed loop systems differ from open loop (deadweight) systems in that they have a means to electronically measure the force being applied during every test and feed (or loop) the information back to the control system. The control system is designed to use the feedback to adjust the force application mechanism to apply, at an extremely accurate rate, the desired force. These systems work so well that today all electronic tensile/compression instruments use closed loop control exclusively. With the teaming up of Instron and Wilson, the ability to adapt the closed loop control effectively to hardness testers led to the development of systems with repeatability never before realized. During the early 1990s this technology was introduced first to Rockwell testers, and later to Knoop/Vickers, as well as Brinell systems. Closed loop quickly gained momentum as a means to achieve extremely accurate and repeatable hardness test results. Today the technology is a popular and widely used format. Now, with significant improvements in recent years in hardness testing

instrumentation, computer hardware, electronics, imaging algorithms and software capabilities, the door has opened to extremely precise and reliable testing processes that provide results more quickly than ever before, often in automated fashion. These components and techniques have proven to be beneficial in raising efficiency, speed and accuracy to unparalleled levels. During the past several years, and no doubt increasingly in the future, more traditional manual test processes have and will continue to rapidly give way to automation in every aspect of the testing process. New techniques in material preparation and handling, mount fixturing, stage movement, results interpretation and analysis, and even reporting, have now been introduced to the hardness testing industry. More and more automation technology is being integrated into many hardness systems using stage traversing and image analysis of Knoop, Vickers and Brinell indentations.

This newer technology eliminates much of the hardware that in the past caused operational challenges and cluttered workspace.

There are a few other terms that also need to be defined: • A dedicated gage is one that is available in a range of predefined sizes and configurations and is used to inspect a single part type or a very narrow range of parts. • A modular gage is made up of standard components, such as pencil probes, contact arms and work rests mounted on a base that allows mounting details to be randomly located and re-located as necessary to inspect a wider range of parts. • A reconfigurable gage is one with easily changed or repositioned arms, contacts and other features that allow it to accommodate a range of similar parts with little time spent between changeovers. • A flexible gage is one that can inspect a range of part types without having to be reconfigured. Unfortunately, there is no industry agreement of these definitions and,

The multidimensional, modular system can be retooled for measuring internal and external dimensional and geometric checks of cylindrical parts such as bushings, hubs and gear wheels.

Data from the gages also are used by the manufacturer to develop predictive maintenance routines for the cell. Source: Marposs Corp.

therefore, a good bit of ambiguity exists when they are used by various manufacturers and operators. The aforementioned definitions are used by us both internally and externally to differentiate the functionality provided by each category of gage. They are independent both of the particular gaging technology being applied and of the manufacturing processes being monitored. SELECTING THE RIGHT GAGE It is very important to begin by defining exactly what the gage is expected to do. For example, specifying a f lexible off-line gage for an application in which a dedicated in-line gage provides the necessary functionality can add both expense and complexity to the installation, with little or no offsetting benefit.

The opposite, of course, also would be true. There are a number of questions that have to be answered when selecting an in-line gage, and not all of them are intuitively obvious. Here is a brief checklist of things to consider: • Production rate. Can we measure fast enough to keep up? • Production size. What is the gage cost per part? Can the gage last for life of the production run? • Number of part types. Can one gage measure all parts? • Differences and similarities between part types. Is it better to make some checks on all part types, or all checks on one part type per gage? • Lot size—changeover frequency. Can the gage be manually retoolable or must it be flexible?

• Part material. Can the gage contact the part or must it use air? • Part configuration and size. Are measurements best performed by putting gage in/on the part, or the part in/on the gage? • Measurements needed to control. Do all dimensions need checking? • Part tolerances—geometric, dimensional, surface finish, flaw detection. How precise does the gage need to be? • Checking parts for function or for process control—what datums to use? The machine tool producing the part may not use the same datums that the end product uses. • Process environment—temperature, temperature variation, cleanliness, light conditions. Does the gage need temperature compensation or a washer/dryer? Can inspection be done using visible light?

• Location in the process, line or cell layout. Is the gage accessible and convenient? • Ergonomic requirements. Does the gage require difficult or repetitive movements? • Price. Is the price within the budget? • Delivery requirements—timing of the project. Can the gage be delivered in time? • Correlation requirements to another measurement source. Different technologies may give different results. • Part condition—surface finish, temperature, cleanliness, wetness. Does the gage need part temperature compensation, a washer/dryer, noncontact technology? • Automated process or manual. Is automatic part handling needed? • Audit checks or 100% inspection. Are the checks safety related, or only for process control? • Maintenance requirements. Does the operator have the time and skills required to maintain the gage? The answer to each of those questions is important and has a direct bearing on gage type and gaging technology best suited for the particular application. Failing to consider and evaluate all of these points (and perhaps others) will likely lead to a less than optimum solution.

For example, there often is a tradeoff between time and cost. Using multiple gages to measure a part generally takes longer than doing all the measurements in one gage. The difference may be between performing the inspection in a few seconds or a few minutes. However, a single gage that measures everything in seconds is probably a custom design that may well cost twice as much as two or three simpler gages. The possibility of purchasing components and building your own gage also should be evaluated. Most major suppliers of gaging technology today offer the “pieces and parts” required, and the savings in engineering cost can be substantial. Naturally, in-house design capabilities will be a major factor in this decision. During this phase of the process it also is important to evaluate a supplier’s product line to be sure it includes all of the potential gage types and measuring technologies that may be suitable for the application. It is the only way to be sure that the solutions ultimately offered are the best available and not simply what’s available from a limited product line.

The programmable machine for inspection of families of shafts incorporates two bidirectional measuring heads to provide gaging flexibility at high operating rates. It can statically or dynamically perform many types of dimensional and geometric checks.

Parts can be loaded into the gage machine either manually or by automation. Source: Marposs Corp.

SELECTING THE RIGHT TECHNOLOGY Finding the right balance between flexibility, accuracy and precision, ease-ofuse and cost is a very important and often difficult task. Different technologies offer a variety of characteristics to help solve this dilemma. Electronic contact-type gages are one of the most widely used categories available today. They are precise, robust, flexible, easy to apply and offer a wide range of measurement. They typically provide a good, economical solution for parts that are likely to be less than perfect when measured because they are able to tolerate contaminants such as coolant, swarf and chips, as well as surfaces that are not extremely smooth due to tooling marks. Air gaging is usually the best inline solution for parts that cannot be touched, and for bores and other details that are too small to accommodate a mechanical gaging probe. While extremely accurate and precise on smooth surfaces, air gaging is an averaging technology so it may not perform

Air-type gages also have an added operating expense because they require a constant supply of clean, dry air. Therefore, it is not possible to operate a precision gage on shop air.

Measurement for Aerospace Manufacturing

The latest optical methods for measuring surfaces can be quite adept at measuring difficult to access surfaces. BY PAT NUGENT

I

n aerospace production, surface measurement often is used for many components, including high pressure hydraulic systems and fuel injection systems. The surfaces on these components often are narrow and difficult to access, frequently residing in small o-ring grooves or at odd angles on the ends of small, difficult-to-orient parts. A wide variety of probes has been developed to measure these surfaces, but fast, accurate staging of parts—and

hence, gaging throughput—remains an issue. At the same time, the need for quality in these components is critical. Seal integrity must be absolute and mating surfaces on connectors must not damage seals. Thus, part tolerances for both form and surface finish on these components are very tight and the need for good measurement process control is rigorous. The latest optical methods for measuring surfaces are sometimes quite

adept at measuring these d difficult-toiffi if ficu fi cullt-t lt-to oaccess surfaces. However, these methods have yet to be widely adopted in the aerospace industry, primarily because they are simply too new. With lives literally on the line and depending on system integrity, engineers are reluctant to risk change, and an “if it ain’t broke, don’t fix it” attitude prevails. Traditional tactile trace methods of measuring surface finish have been validated by many years of compiled data and successful use. To gain similar certitude, optical methods will no doubt have to undergo years of parallel testing to achieve the same confidence level. Nonetheless, there are steps aerospace production engineers can take

www.qualitymag.com

 The measurement of surface roughness in bores often is difficult due to the size and depth of the bore. In this example, a dedicated bore fixture, mounted on the front of the handle assembly, accurately positions the probe in the area to be measured. During entry into the bore, the probe is in a protected position. A mechanical device allows the probe to drop into measurement position only when the plug is fully seated against the front of the bore. No operator technique is required for orientation or protection of the measurement probe. Source: Mahr Federal

to improve the speed, accuracy and cost effectiveness of the measuring process while using traditional tactile methods. Consider three such approaches: one in which form and surface measurements are merged on a high end metrology system; a second in which parts are more efficiently staged for measurement on such a system; and a third in which the surface finish gages are customized to allow better access to the difficult to measure features on the parts. All three approaches demonstrate improved ease of use and consequent reduction in operator error, better gage repeatability and improved measurement throughput. MERGING FORM AND SURFACE We have written before (Quality Magazine, September 2006) that, while there are often fundamental differences in the design and manufacture between instruments that measure form and those that measure surface finish, the only real difference between the measurements themselves is the frequency or wavelength of the data set used. In that article we described how measurement data is filtered by wavelength (also known as setting the cutoff in measurement parlance). Within the limitations of a probe or stylus tip and the device used, any part trace includes an amalgam of a nearly infinite number of different wavelengths present in the path being traced. These, in turn, reflect characteristics imposed by the manufacturing process. Traditionally, this data has been divided into three categories: roughness, waviness and form. Shorter wavelength data tends to reflect surface roughness characteristics imposed by machining operations such as turning, grinding or polishing. Waviness involves longer wavelength data and may reflect conditions caused by instabilities in the machining process, such as imbalance in a grinding wheel or worn spindle bearings. Long wavelength data tends to reflect errors such as lack of straightness in the guide-

There are many applications where it makes more sense to measure parts directly rather than take them into a metrology lab or mount them on a gaging system.

KINEMATIC STAGING IMPROVES EFFICIENCY Combining form and surface can reduce the number of required setups and improve the measurement process, but staging small complex parts remains difficult. If you have a plunger about the size of a pen, for example, with a small groove on its side about 1 millimeter across, and it has to be staged in a particular orientation and at a precise angle to run a surface finish trace along the bottom of the groove, the setup is going to require an experienced operator, it is going to take time, and it is going to be prone to measurement error. But the process can be improved. Fixturing systems are routinely designed for companies, which improve the efficiency of staging small complex parts by orders of magnitude. There is no technical wizardry involved, and these systems do not break new conceptual ground. In fact, it is rather the opposite: these systems succeed because they are based on good, solid mechanical design principles and use basic kinematic mounting techniques. The idea is simple. For each part, one or more mounting fixtures is custom designed, depending on the number of features that need to be accessed and measured and the orientations those measurements require.

Historically, form measurement machines were designed to measure longer wavelengths, utilizing longer spacing (typically 5-10 microns) between data points and some inherent filtering of short wavelength data within the instrument. Measuring surface finish characteristics according to accepted ISO, ASME and JIS standards requires an increase in the resolution of the typical form measuring instrument and adherence to the filtering requirements of these standards.

mount in another base fixture designed to mount on the measurement machine. The operator simply puts the part in the fixture, puts the fixture in the base, presses the appropriate measurement icon on the touch screen and the system takes the measurement. But while the idea is simple, the implementation requires careful design and planning. In order to be fail-safe, these fixtures must be designed— insofar as it is possible—such that the operator cannot put the part in the fixture wrong and cannot mount the fixture into the base wrong. The ultimate goal is to create a solution that requires no tools for mounting the part in the fixture and none for placing the fixture on the machine. The fixture should be designed in such a way as to ensure that the part is firmly held once it is inserted into the fixture and the holding force is operator independent. Typically this is accomplished with springs to set the holding force. This ensures that the part is always firmly held and the operator cannot forget to tighten some clamping mechanism. Furthermore the clamping force is controlled so that nothing can be over-tightened and distort the part for measurement. Such fixturing systems are the best way to ensure reliable functionality in a production environment. By using them, operators can make highly

sophisticated form and surface finish measurements quickly, easily, and most importantly, accurately. TAKING THE GAGE TO THE PART While most of the focus in the preceding examples has been on small, easily transported parts, there are many applications where it makes more sense to measure parts directly wherever they are rather than take them into a metrology lab or mount them on a gaging system. There are several rules for the design of such systems. First, in addition to shop-hardening the gage, the design must protect sensitive probe and drive components. It must allow access to the features to be measured. It must be designed to eliminate operator error as much as possible, and of course, it must be fast and easy to use. One approach has been to develop a series of modular fixtures, keyed to the requirements of specific components, that enable operators to simply place the fixture in the area to be measured, and with the touch of a single button or two, affect the entire measurement process. The fixture itself takes care of accurately positioning the gage, engaging the probe and taking and recording the measurement. A good example of this is the measurement of surface roughness in bores. This often is difficult due

www.qualitymag.com

Fixturing systems are designed to improve the efficiency of staging small complex parts by orders of magnitude. These systems succeed because they are based on good, solid mechanical design principles and utilize basic kinematic mounting techniques. For each part, one or more mounting fixtures was designed. These, in turn, mount in another base fixture designed to mount on the measurement machine. The operator simply puts the part in the fixture, puts the fixture in the base, presses the appropriate measurement icon on the touch screen and the system takes the measurement.

to the size and depth of the bore. Typically, positioning the drive unit often leads to probe damage and drive unit positioning problems. The bore fixtures were designed to eliminate these problems by automatically positioning the measurement probe in the correct orientation. In one example, a dedicated bore fixture, mounted on the front of the handle assembly, accurately positions the probe in the area to be measured. During entry into the bore, the probe is in a protected position. A mechanical device allows the probe to drop into measurement position only when the plug is fully seated against the front of the bore. No opera-

tor technique is required for orientation or protection of the measurement probe. Thus, by a combination of merging form and surface finish measurement, efficiently staging small complex components using intelligent fixturing, or designing gages that more efficiently measure parts directly, traditional tactile methods of surface finish can be employed more quickly and efficiently, and even with improved accuracy.

DOCUMENT OC M N CON CONTROL O IS ESSENTIAL Document control, as with many other systems, is more successful if it is simple, intuitive, user-friendly, easy to monitor and effective at preventing the use of incorrect documentation. Control of documents should be thought of as one of the cornerstones of an effective quality management system. Certainly it is not a glamorous activity. However, document control is an essential preventive activity that, when effectively managed, can ensure that once approved, current documents will be used throughout the organization. Inadvertent use of out-of-date documents, procedures, work instructions and the like can have significant negative consequences on quality, costs and customer satisfaction. There are numerous situations that can be used as an example of what can happen when the proper documentation is not available.

IT’S AN INVESTMENT Because of the importance to the business, more and more organizations are investing heavily in dedicated staff and detailed procedures. In the past, document control was an “add on” to someone’s responsibility. Today, it is an

SOFTWARE & ANALYSIS area of growth in the jobs market; with high demand and potential high pay that crosses over to multiple industries. However, there is really no formal training available. There are no college courses, let alone a degree program, which directly train anyone into this profession. People working in this arena have had to learn the skills and techniques on their own. With many customers and suppliers requiring quality management systems in order to be certified, there have been a plethora of specialized software programs created to assist them in the control of their QMS and other business-related documents. This has been helpful, but it brings about other required skills in managing the overall system, which will not be discussed in this article. Information contained in documents, procedures and work instructions drives nearly every action in any organization. The ability to control this information means the difference between success or failure. Control of documents, therefore, remains the single most important quality assurance discipline.

It is easier to control a smaller number of documents than a large number. While this seems elementary, there are many examples where organizations appear to think the quality of their document system is directly proportional to the quantity of documents and records. A good document control system starts with document design and an understanding of the hierarchy and structure of documents. Document control administrators should be concise and work to keep the documents simple and multipurpose, when possible. An annual documentation review to uncover redundancies, obsolete documents and opportunities to consolidate will enable an organization to keep their documents lean, while effective, but with less cost. Recently, a quality manager in an ISO 9001 certified organization worked to streamline the company’s document control system. With the goal of reducing administrative costs while maintaining an effective document control system, the quality manager was able to implement a 43% reduction in their overall costs to maintain and control documents.

BRING ON THE HIERARCHY In order to bring about consistency and interrelationships governing an effective document control system, there needs to be a system or hierarchy. Arguably many organizations have been in existence for decades, managing their processes without much, if any, formal documentation. Some of these organizations continue to ship products that meet their customers’ specifications. However, in today’s environment, significant changes are impacting every organization. These dramatic changes are forcing organizations to change in order to remain competitive. These changes are causing organizations to become much more formal and structured. One model for structuring documentation is the pyramidal structure, with each level in the structure interlocking with and supporting the next higher level. This model is effective because it offers a logical arrangement that clarifies authority and interrelationships of each document. Lower-level documents must agree with requirements of related

higher-level documents. Similarly, higher-level documents typically reference lower-level documents to drive connectivity. The message in many organizations is that lower-level documents cannot be in conflict with upper-level documents. The goal is not to be inflexible, but to ensure an organization is performing work in a consistent and efficient manner to deliver customer expectations. While the basic tenets of document control are fairly simple, implementing and managing an effective and efficient document control system can be a challenge. Documents are not individual, stand-alone elements of the management process. They are interrelated, formatted in different media, and typically controlled by various and distinct functions. Keeping critical information current, in the right hands of the right people at the right time, requires more than just signing off (approving) on procedures. Document control is essential, but where should you begin? WHERE TO BEGIN Maybe the simplest suggestion is to use the ISO 9001 quality management system requirements even if an organization is not interested in working toward a certifiable quality management system. ISO 9001 requires, and always has required, an organization to have a documented quality management system, and not a system of documents. It is very flexible, so it can be adapted to fulfill most organizational needs. Simply work down the list of document control issues outlined in the requirements and briefly describe what the organization is doing for each one. Keep it simple and avoid creating too much bureaucracy. An effective document control system will provide documents to users quickly and not slow the process with lengthy and non-valueadded procedures. Philip B. Crosby once said that, “an organization that establishes a quality program will have the ability to do what it agreed to do.” Isn’t that what a document control program is all about? It is a direct reflection on the organization’s personal integrity and intensity about getting things done properly to satisfy the needs of their customers. A effective document control system results in an organization having the

the quality of materials coming in the door must be improved before “we can make real improvements.” How many times has your organization sat around and argued and complained that your customers do not have their ducks in a row; they cannot ever seem to place an order error free; or the ultimate complaint, “We don’t have a clue what the specifications from this customer are?” If your team is sitting around having these discussions about your customers, wouldn’t it seem that your suppliers might be saying the same thing about you? Using the lean philosophy of improving every day, attack what you control. Right now—not tomorrow or the next day. Not after your suppliers get their acts together. Now. Not after your customers understand what it is that you need from them and can send you the correct information each and every time. Now. Sounds simple enough. And it truly is. READY, SET, GO So how do you get started? 1. IDENTIFY THE ISSUES Spend time identifying the issues by utilizing a problem-only brainstorm session with your team. Be sure to include representatives from all affected areas—purchasing, production,

Where should you start to improve quality throughout the supply chain? Whoever you are, whatever your job, it starts with you.

engineering, quality and sales—on the team. Use a facilitator to keep the session moving forward and to avoid members trying to solve problems on the spot. This meeting should generally last less than 30 minutes. If the list gets too large or the issues too deep, remind everyone that you do not have to solve all the problems of the world at once.

www.qualitymag.com

Continue to look around for quality issues that you can improve and repeat the cycle time and time again. The cycle must become the culture of your organization to truly be successful.

2. CATEGORIZE THE LIST Review the list and quickly assign each item to one of three categories: supplier, internal or customer. Do not allow anyone to place an item into more than one category. If they try, and one category is internal then place it in the internal bucket. For other items that are both supplier

and customer issues (if there are any), allow the person that placed the item on the list in the first place the task of deciding into which bucket it should be placed. After the items are all categorized, take both the supplier and the customer lists and parking lot them— set them aside for now and revisit them when you are ready to work on step 5.

MANAGEMENT 3. IDENTIFY ROOT CAUSE Take the list (or bucket) of issues that have been categorized as internal, and before performing root cause analysis, prioritize the list based upon whatever criteria your team chooses. Then, and only then, begin conducting root cause analysis on each item on the list from most important/critical to least important/critical. Whether you use the 5 Whys method, Ishikawa Diagram, Pareto Analysis, Kepner-Tregoe RCA or some other tool to determine root cause, make sure you complete this step. It is critical to systematically attack problems based on facts, not hunches or opinions. 4. IMPLEMENT CHANGE WHERE YOU ARE IN CONTROL As you identify root cause and determine what changes must be made to correct the problem, do not wait. Using lean logic, once you know what to do—do it. Do not think you need to implement change according to priorities. It may take considerably longer to identify the root cause of

your highest priority quality problem than one much farther down on the list. Use the lean mindset of making something better today—right now. Your goal at this stage of the game is to make improvements as quickly as possible. The improvement may not be perfect, but if it is better than it was yesterday, you are headed in the right direction. 5. LOOK FOR PARTNERS, BOTH CUSTOMERS AND SUPPLIERS When you begin to notice that quality concerns in your small piece of the world are getting better, it is time to start spreading your success outward. First, to other parts of your organization, and then to your suppliers and customers. You do not have to be perfect internally before you start spiraling out, but your improvements had better be noticeable. Noticeable to your internal customers as well as your ultimate customer. Noticeable not just to your internal supplier, but all the way back through the supply chain. People need to be holding you

up as a model for quality improvement. That does not mean error-free, it simply means that the changes are real, apparent and measurable. This is the point in the process when you revisit the parking lot looking for opportunities with suppliers and customers. This also may be the most critical part of the supply chain quality improvement process. Looking over the two categorized lists identify other organizations that appear to the team to already be partners, or their mindset is such that your team members believe they are good candidates for partnering. You may want to seek information from others in your company for more input on this subject. Once identified, find issues on the list from that particular bucket for the candidate company that can be improved. Your goal is to find common ground with the supplier or customer where you can work with them to solve quality issues that make both organizations better, more profitable companies.

apart from their competition. Pelco, the 2010 Quality Magazine Plant of the Year, is focusing a considerable amount of effort to create partnerships with both suppliers and customers in pursuit of improved supply chain quality. 6. HELP THEM HELP THEMSELVES AND YOU While Pelco has spent some time working with several customers to help them establish lean supermarkets and to use kanbans to reorder product, the most powerful results to date have come from partnering with suppliers to improve the front-end of the supply chain. Working with Tower Extrusions Ltd. (Olney, TX), Pelco’s lean experts toured Tower’s facility in Texas. From this tour and the candid discussion following, Pelco worked with Tower management to create a game plan where Pelco staff conducted a lean training class, facilitated a lean kaizen event and worked with the Tower management team to identify an internal lean facilitator. With a game plan in hand, Tower Extrusion is now heading into its own

lean journey. Significant cost savings have already been realized through the training and assisted kaizen events. Pelco, in return, has seen improved quality and reduced lead times on product purchased from Tower. Even though Pelco staff has repeatedly explained to Tower management that this is a win-win partnership, Tower’s General Manager Mark McClelland continues to be amazed. “I just can’t believe that one of our customers would come help us. And then when they loan us their managers and lean experts to get us started, they only ask to be reimbursed for actual cost in return,” he says. “We can never repay Pelco’s assistance. This partnered effort has set the stage for our lean and quality journey for years to come.”

Continue to look around for quality issues that you can improve and repeat the cycle time and time again. The cycle must become the culture of your organization to truly be successful. So, do not sit around waiting for your suppliers to get quality right first. It starts with you. With a little luck and a lot of hard work you will soon be joined by customers and suppliers working to achieve the best quality for everyone. Q

7. REMEMBER, IT IS CONTINUOUS IMPROVEMENT Even as success after success is realized, remember that this is continuous improvement. The effort started with you and what you could affect immediately. And ultimately it will come full circle.

exercise. According to Maurice Leger, senior process quality engineer at Tegra’s Dartmouth, MA, facility, this was not the case. Dartmouth has just upgraded its vision inspection capabilities by adding a new The L.S. Starrett Co.’s (Athol, MA) Galileo EZ200 manual vision system and an automated Starrett Galileo AV 300 multisensor system. This acquisition allowed Tegra to augment or replace reliable older microscopes, comparators and vision systems that have been used at the plant for many years, with systems that are far more accurate, repeatable, and easier to program and use. Leger, who led the search during which his team evaluated several brands of multisensor systems, explained that new vision-based systems would be involved in diverse applications. These include first piece inspections, traditional in-process part validation, random roving inspections, mold validation studies (for the plant’s newly launched clean room) and Six Sigma manufacturing process qualifications, in addition to generating geometric data and analyses that could be shared across multiple divisions and with the company’s Genesis Tech Center in support of rapid response manufacturing projects. So finding vision-based measurement systems that provide the best fit for all of these present and anticipated uses was a very exacting process. The primary driver in acquiring the multisensor measurement capabilities was the expansion of the division’s focus from the precision grinding of needle products into Class 8 clean room overmolding of completed products incorporating the needles and subsequent medical device assembly and packaging, including Class III medical devices. Leger says, “The Galileo AV 300 was bought in parallel with the decision to steer the business toward clean room injection molding. Mold validation

studies performed at Tegra Medical involve making tens of thousands of parts very quickly and making hundreds of measurements at welldefined intervals. The object of the game is to determine which settings in the machine I will use to get the best results out of every cavity. For this purpose we needed a system that is fast and easy to program, extremely accurate and capable of automating the

measurement of large numbers of parts in a very small window of time.” Today, with the AV 300 system it takes a few hours to write the program to set up a large mold validation during which the same two or three CTQ (critical to quality) features are measured on a large number of parts. Programming is simple because it keeps all the needed tools, directly on the desktop just

as they are with modern computeraided design (CAD) systems. Because the system feeds all the data into an Excel spreadsheet, transcription errors are eliminated. It takes about a day to measure the parts, collect the data and complete the study. This reduces the mold validation process by days while improving accuracy and eliminating many sources of potential error.

The AV 300 system at Tegra Medical is equipped with a tactile probe that can reach in and collect data from areas of the part where the geometry obstructs the video sensor. In the past, inspectors had to cross section parts to measure these areas. Cross sectioning is a very labor intensive and delicate procedure that adds hours to the measurement process. Tegra hopes that the AV 300 will dramatically reduce need to crosssection to mold validation and process studies even faster. While the company was evaluating advanced video measurement systems for its laboratory, it was looking to upgrade the manual measurement capabilities that relied on optical equipment of a previous generation. Operators employ these systems on the shop floor, so they have to be rugged, fast and easy to use. Leger discovered that it was possible to emulate the cross-hair alignment mode of operation used by the older style equipment with Starrett’s Galileo EZ200 manual video measurement system. Therefore,

operators got the benefit of higher accuracy, repeatability and more magnification with a system they could be comfortable with after just a few minutes of training. Because quality operations management spans all of the Tegra Medical’s divisions Leger wanted to confirm that this style of measurement would suit the needs of everyone working on projects that span multiple divisions. So shortly after installing his systems in Dartmouth, he had the quality team

from the Franklin, MA, plant come in to look at what he was doing. They liked what they saw. Soon they were asking Leger to do some profile measuring for them. It was not long before the Franklin plant installed a Galileo EZ200 system of its own. Now Tegra’s Dartmouth facility has very accurate video measurement tools that it can use not only to meet today’s needs, but also adapt to future requirements as the company customizes and fine-tunes manufacturing processes to meet the needs of its exacting customers. Leger says, “When the Galileo AV 300 first came in I told just about everyone we were about to land a spaceship in the middle of the plant. It is much more accurate and capable than systems of the past.

“The team listened to what we wanted rather than forcing us to listen to what they could offer; that was quite refreshing. They also said, ‘We understand exactly what your needs are and what your customer base is going to need.’ A package was then tailored to suit Darchem’s requirements instead of offering us a one-size-fits-all package.” Marshall says that he also liked how intuitive the software was to learn, enabling inspectors to put it to immediate use in the FAI process, as well as how easily the software can be adapted to the unique requirements of each of Darchem’s customers. “We knew once we tried it that it was very much the software package we wanted to bring in. We have been able to demonstrate to our customers that Discus was the right company to partner with,” says Marshall. Marshall says that Darchem now recommends Discus to its suppliers based on proven experience, and he is confident other UK companies could benefit from using their software. “In fact,” Marshall notes, “some of our key customers have also selected Discus as their preferred provider of electronic first article inspection reports (FAIR).” A major benefit of the software package for Darchem is time savings. Marshall notes, “We were able to reduce the time of the first article inspection process by 50% initially, and since then, 60% to 70%.” He says that the software takes a great deal of time out of the laborintensive preparation process, which can involve gathering a large number of dimensions and specifications. Darchem delivers FAIR right the first time, and Discus has allowed Darchem to save a substantial amount of time. “The fact that we are able to deliver the first article inspection reports right and in a timely manner plays a pivotal role as program timescales are often under pressure at this early stage. It gives the customer the confidence that we have the ability to manage the proj-

ect effectively…and that helps satisfy the customer that they’re dealing with the right supplier.” As a result of the time savings from using the software, Darchem realized a return on investment in six months, Marshall says. “I was expecting ROI in the first year. That would be good. But we were able to demonstrate to the directors here at Darchem a pound for pound savings—the Discus software gave us a six month ROI, in labor savings alone.” From the good experience of the Aerostructures division, the company has purchased additional licenses for its other divisions, which are now also benefiting. Marshall points out, “Customer support has been outstanding. In many cases, it has involved getting answers the same day. This allows Darchem to complete the documentation and deliver the first article reports to the customer on time. We didn’t expect to get answers the same day. That is impressive, particularly since we are located in the UK

CMM Learns New Tricks by Moving to CALYPSO Software DeZURIK is a global leader in manufacturing water and wastewater treatment valves as well as many other valves. They have been using a Brown and Sharpe CMM (coordinate measuring machine) system for 11 years for various quality measurement processes. In 2010 DeZURIK had the need for decreased part programming times, reduced operating costs and they were also due for a software upgrade on their current measurement system. Cone and angle measurement complications were of special interest and they were curious as to how CALYPSO would handle these measurements. After software demos and cost comparisons, DeZURIK decided to purchase a CALYPSO software upgrade from Carl Zeiss. CALYPSO would easily work on their Brown and Sharpe CMM, would decrease part programming time and would cost less than an upgrade on their previous software. The CALYPSO software is very user friendly and easy to use. “With our previous linear programming code setup, if you didn’t write the part program, you really had to study it to determine where the measurements were coming from,” says Keith Feddema, quality engineer at DeZURIK.

Benefits of CALYPSO’s objectdriven measuring tasks and visual metrology for DeZURIK: • multiple operators can easily use programs • part programming time reduced 50 percent • angles and cones easily analyzed with different calculation tools • measurement plans easy to organize, no complex code • printed graphics improve measurement communication with R&D and customers • can perform more first article inspections DeZURIK is now able to use CALYPSO software for even more measurements in various applications.

Cutting the Cables

Cases for the high-efficiency gearboxes produced by Fertigungstechnik Nord in Gadebusch, Germany, are machined from solid castings at an annual production volume of over 280,000 units. The company has extensive experience with networked automatic gauging systems used in the shaft manufacturing area. These systems automatically measure production shafts and provide compensation feedback to the controls to maintain quality. However, that approach is not feasible in the case machining area. Equipping all of the machining centers with fully automatic measuring devices would be economically unfeasible. But the company has been able to obtain many of the same benefits by changing from conventional cable-connected plug gauges to M1 Wave Wireless gauges from Marposs.

www.qualitymag.com

The most obvious benefit of a wireless solution is the elimination of cables, and that is no small advantage when a typical workstation has a dozen or more gauges, each with several yards of cable attached. The safety impact of removing those cables from the working environment is self-evident, and eliminating the maintenance cost associated with them produces significant operating cost savings as well. In addition, eliminating the cables also eliminates a major source of interference and incorrect gauge readings that cost employees precious time at the machines. The new wireless gauges have substantially reduced error rates. Combined with the display electronics in the form of networkable PC technology and the process-oriented software solution, the new measuring systems ensure a high measuring reliability. In addition, Nord has implemented traceable documentation of the measured data that are manually collected in the case manufacturing plant.

DID YOU KNOW…

…that a HEIDENHAIN GAGE-CHEK metrology digital readout (DRO) is a vital component in the new and truly unique in-process honing and air gaging system now available to high precision metalworking businesses? Called PAGS (Precision Air Gage System), this new technology is available from Bates Technologies LLC in Fishers, Indiana, and is being installed for its customers by select global machine tool builders such as Mazak Corporation and others who want to offer a superior, integrated honing and gaging system directly on a machining center. Typical honing systems are standalone, dedicated machines. The flexibility provided by the in-process PAGS honing system incorporated into a machining center effectively eliminates the need for the

dedicated equipment as well as streamlines the process resulting in a significant cost-savings for the end-user. “This really has been a collaboration of experts over the last few years in order to enable this important paradigm shift in honing and air gaging for use on flexible and agile platforms,” said Darrell Day, president of Bates Technologies. “The overwhelming support and expertise from HEIDENHAIN has contributed into allowing our PAGS to talk to our customers’ PLCs and make this truly an in-process system.” The PAGS in-process gaging system for use on CNCs includes the use of a controlled air pressure. This information is passed onto the GAGE-CHEK unit which has been programmed to monitor the changes in bore size during the process. This information is visually available to the operator through the unit’s DRO function. As the bore size grows larger with each stroke of the honing tool, the gaging unit mounted on the side of the machine displays its dimensions in microns, and when the correct size is reached, the CNC machine PLC is fed information from the GAGE-CHEK to notify it to complete its cycle, and automatically stops.

This makes the process faster and reduces mistakes.” He continued, “We aren’t drawing free, yet, but like the rest of the aerospace industry we are striving to implement model based definition to achieve its many benefits.” For SpaceX the most important benefit is time. Model based definitions (MBD) with profile tolerances eliminate the time to document an engineering drawing; reduce the time to create inspection plans and reports; and accelerate identification and resolution of manufacturing issues.

Assuring Performance of Long Gage Blocks By: Amosh Kumar, Laboratory Manager Mitutoyo America Calibration Laboratory, Elk Grove Village, Illinois McNeal Tool Company of Cedar Rapids, Iowa, a wholly owned subsidiary of Mid Iowa Tools, Inc., specializes in the sales and support of precision metrology instruments and services. This includes provision of gage calibration services to a national manufacturer of window and door products that are sold into residential and commercial markets. According to Wayne Schneider, McNeal Tool Field Application Engineer, “Many of the customer’s products include wood and extruded or roll-formed materials processed to length using tenoners, molder/profilers, or saws. The length of these pieces can measure from around 90” to 140” or more, with tolerances typically kept to within ± 0.002”. To help keep machining processes centered on nominal values, the customer utilizes an SPC measurement routine that includes periodic use of long, single-axis measuring tables specifically designed to verify accuracy of long workpieces. The measuring tables are about 12” wide, up to 140” long, and equipped with digital readouts. Accuracy of the measuring table set-ups is regularly verified utilizing an “assembly” of the longest available, standard gage blocks – these come in kits, generally with lengths of 5”, 6”, 7”, 8”, 10”, 12”, 16”, and 20”. These long gage block assemblies must themselves be periodically calibrated as error accumulates over time. Error can be introduced by: disassembly and re-assembly, nicks, burrs, dropping, oil and dirt build-up, corrosion, etc. To reduce inaccuracies, each gage in the set of blocks making up a long gage block assembly must be individually calibrated. Schneider explained that selection of a calibration services provider became increasingly important to the window manufacturer, saying, “Our customer had tried a number of calibration labs but couldn’t get consistent results. This was a real problem since inconsistencies are ‘multiplied’ by the number of blocks in each assembly. Finally, the window manufacturer settled on the Mitutoyo America Calibration Laboratory in Elk Grove Village, Illinois for providing the necessary level of performance.” The Mitutoyo America Calibration Lab uses reference masters that are directly traceable to NIST (National Institute of Technology and Standards).

To achieve high accuracies and low measurement uncertainty levels, the lab calibrates all instrumentation in a Class 10,000 certified clean room environment. When calibrating long gage blocks, temperatures are kept at 20º C ± 0.25º with relative humidity controlled between 40% and 60%. Access to the clean room is controlled by a positive pressure airlock to prevent entrance of outside air. Laboratory Best Practice procedures for measuring long gage blocks also include: • Verification of “single-point temperature stability” of the measuring station whereby temperature variation is verified to be less than 1/10 degree C per hour. • Real-time monitoring to make sure temperature gradients in the vicinity of the workstation remain consistent for the entire eight hours or more required to calibrate eight-piece long gage block sets. Schneider commented, “From choice of block material to the care taken in calibration lab procedures, our customer could see the how the benefits of Best Practice calibration translate from gage blocks, through measuring tables, and on to higher quality finished parts with lower rejects.”

Scienscope has solved these problems for numerous medical device manufactures by providing x-ray systems that allow the user to quickly inspect an assembly and make an informed decision in the control of a process or repair of the assembly. One manufacture was doing a visual inspection and electrical test before quoting the customer on the repair of a very expensive encapsulated assembly, by using the x-ray system for initial inspection they were able to reduce their labor costs in the evaluation phase and provide the customer with a faster and more accurate repair quote. Another manufacturer was visually inspecting over molded components and using a time consuming process of painstakingly removing the over molded materiel to revel the suspect area, x-ray inspection saved tens of thousands of dollars in overtime costs per year.

Integrating Your Quality Management System Solution & Implementation The company selected Intelex’s Integrated EHSQ Management System to do the job. Completely web-based, the system enabled employees across all locations to input quality, safety and environmental data into one centralized portal where it is easily accessed, reported, managed and analysed. Historical data was imported into the system, users were trained on key tasks and the system was swiftly deployed across all locations.

Though a standalone quality management system will suffice for many organizations, those that strive for continual improvement and understand the real value of data visibility employ an integrated approach to managing environmental, health, safety and quality (EHSQ) data. This is exactly why one of the world’s largest beverage manufacturers approached Intelex after identifying the need to unify isolated quality, environmental and safety systems into one integrated solution. Business Objective Since employees used different systems to manage EHSQ activities, organizational data existed in silos, could not be cross analyzed and required multiple personnel to access, retrieve and prepare it for management review. A centralized, user-friendly software solution to unify performance data and standardize processes was clearly needed.

Results Having all EHSQ performance data contained within one system provided the organization with real-time, 360-degree visibility. This allowed for faster and more extensive reporting capabilities of key operational data, better educated decision making and improved response times. Management can easily view dashboards instantly displaying any organizational performance data desired. The system’s ease-of-use resulted in more incidents and nonconformances being reported, allowing clearer identification of trends and prompt resolution of issues.

Optical shaft inspection is a H-O-G “We measure diameters to 4 microns with a gage R&R of 5%,” reports Clay. “You can’t touch that anywhere.” Hommel-Etamic’s Opticline noncontact CNC shaft gaging system measures form, dimensional, and positional tolerances of shaft-type parts in submicron detail with a maintenance-free two-camera system, recording results instantly. “With air gaging or hard gaging, there is a lot of setup and timeconsuming changeover, but with the Opticline,” Clay said, “I can change programs in about 15 seconds and be ready for the new part number. Flexible chucking helps also.” To create a program, Clay scans the part with the Opticline cameras, establishes a length of scan, and then starts a measurement cycle. “To accomplish the shaft measurements with air gages or ring gages, you would have multiple gages, which require setup, mastering, and maintenance. This adds up to greater cost over 3-4 shaft designs with a couple of sizes of each,” Clay said. The family of turbocharger shafts produced at Cummins Turbo Technologies, Palmetto, SC, have up to 11 diameters and various lengths—a complex part to inspect consistently and at rates that keep up with production. But Clayton Butler, metrology technician has a solution that has been working on the Cummins shop floor alongside the grinding machines for several years. He calls it his HOG -- the Hommel Optical Gage. Machine operators use the Opticline from Hommel-Etamic America to measure a shaft and turbine impeller wheel assembly for the turbochargers it produces-- diameter, runout, straightness, length. The staff also uses the gage on the shop floor alongside the grinders to measure an impeller mounted on an arbor. Each part is measured between centers in less than a minute.

It is unique in that it offers two measuring units easily swapped out by hand as needed – faster, simpler and more accurate than competitors’ gages. Compared to other gages, it has a stiffer measuring axis, hardened surfaces and easy adjustment to measure width at different inspection points. In the American Le Mans Series, the race cars go rain or shine. Porsches’ previous gages produced readout errors or total shutdown at inspection in wet conditions.

Multi-Sensor Machine Replaces CMM To meet the needs of new medical customers and to stay ahead of competition, a precision plastic injection company in Santa Rosa, CA searched for a multi-sensor inspection system. They needed to measure smaller features, reduce programming time, reduce measurement time, and improve operator/programmer easeof-use compared to their CMM. The company selected the Micro-Vu Vertex 320 vision system with a 4-station touch probe kit and a 12"x12"x6" measurement capacity. The company retired its CMM within months. The company's metrologist began programming parts using Micro-Vu's InSpec Metrology Software during the first demonstration. Small holes, angles, gaps, and steps are programmed and measured in seconds. Previous "operators" become "programmers" with InSpec's point-and-click programming. Parts from multiple mold cavities are measured in a single inspection program and setup. While the Vertex measures multiple pieces, the operator completes other quality/inspection tasks. When the inspection program is complete, the operator can quickly review toleranced and exported features in a summary window. If needed, the operator can edit tools from the multi-capture cache of images.

Tools can be reviewed and edited even after parts have been removed from the stage. When the company expanded, it purchased a second Vertex. InSpec's lighting calibration ensures that programs from one machine can run on another. Also, the system price with the 2-port touch probe kit, didn't require a VP's signature. Micro-Vu Corporation was established in 1959 and is a leading manufacturer of optical comparators, video systems, and multi-sensor measurement systems. Micro-Vu machines are designed, manufactured, and assembled in the United States.

Increasing Metrology throughput without compromising quality

Within the custom manufacturing industry each job presents new challenges and every application requires special attention to detail. There does seem to remain one constant however… “Deliver highest quality parts at lowest possible cost”. To achieve this goal, companies continue to develop their metrology capabilities looking to achieve faster inspections without sacrificing the quality assurances delivered to their customers. Vision-based measuring systems are a key component in achieving quality-control productivity as vision-based systems typically surpass contact metrology alternatives in speed and throughput, while maintaining precision and capturing comprehensive data. Additionally, vision metrology systems eliminate potential part damage from contact inspection. The new Fetura® Vision Metrology Systems from Qioptiq represent a vanguard approach to optical measurement, combining years of optomechanical expertise with cutting-edge software and robust mechanics to deliver unparalleled productivity, flexibility, and precision. At the heart of the system is the market’s fastest and most precise zoom imaging lens technology. Nearly 10-times faster than conventional zoom lenses across a 12.5X optical zoom range, Fetura images from low to high magnification in less than 1-second (approaching that of digital zoom speeds). This important feature affords users the ability to perform critical quality inspections in shorter cycle times with greater

operational savings… a value they can pass on to their customers. In one particular case, a customer required 100% parts inspection of a high-volume medical components process. Metrology speed and accuracy gains were a necessity in achieving maximum throughput and ultimately greater quality and net productivity. The Fetura System’s imaging agility and high-speed mechanics, combined with multi-part fixturing readily achieved the customer’s aggressive inspection throughput and productivity goals. In this case, each individual component required measurements to be taken at multiple magnifications. With the Fetura’s unmatched imaging speed, the customer reduced their inspection time for each lot by more than 8 minutes. This translated to 33% more parts inspected per shift and ultimately more than $31,000 projected savings in the first year of production in inspection costs alone. This increased speed at inspection also means savings across the complete manufacturing process. In addition to its unmatched speed, the unique design of the Fetura’s imaging lens enables it to maintain optomechanical precision over 1 million zoom cycles with virtually zero performance degradation. This means prolonged and consistent precision and accuracy over the extreme rigors of a high-volume inspection application like the medical components case cited above, without the need for recalibration and uncertain software compensations. The Fetura Vision Metrology System is a robust measurement workhorse that meets the needs of demanding global manufacturing markets. The Fetura Vision Metrology Systems offer an alternative in the metrology industry that is measurably different.

OPTICAL TABLE ISOLATION SUPPORT SYSTEM

NONCONTACT TUBE INSPECTION SYSTEMS

Due to its Minus K negative-stiffness technology, the MK52 optical table isolation support system achieves low net vertical natural frequency without limiting its ability to support static loads. Horizontal isolation is provided by beam columns connected in series with the vertical-motion isolator. When adjusted to a ½ hertz natural frequency, the unit achieves 93% isolation efficiency at 2 hertz, 99% at 5 hertz, and 99.7% at 10 hertz. The system can be configured for a variety of locations and applications, wherever external vibrations can adversely affect the operation of sensitive equipment. The unit is available in table sizes up to 4 feet x 8 feet with gross load capacities up to 2,000 pounds. Tables are constructed with a 3⁄16 -inch thick ferromagnetic stainless steel top skin, 3⁄16 -inch thick carbon steel bottom skin, and plated-steel precision honeycomb core.

The new line of noncontact tube inspection systems provides solutions for an array of tube and wire bending applications including tube inspection, bend correction to reduce scrap, reverse engineering and fixture verification. A range of noncontact, infrared probes provide operator-assisted visual notification via a laser stripe indicating the measured area. The operator can view where data points are acquired on a tube or wire during the inspection process. The probes are interchangeable with traditional ball probes without the need for re-calibration, delilvering plug-and-play capability. Brackets, flanges, bosses or other geometric features can now be included in the measurement routine. The noncontact probing feature enables measurement of the most flexible tubes or wires from 4 millimeters to 130 millimeter in diameter, without risk of deflection.

Recently, N Newswise reported that researchers from UCL UCLA and the University of California completed a ten-year clinical study of 53,000 current or heavy smokers that concluded that those who wh were screened with low-dose spiral CT scann scanning had a 20 percent reduction in deaths from lung cancer apposed to those who were screened by chest X-ray. According to the reporting, the study—called the National Lung Screening Trial (NLST)— was conducted among this high-risk group to compare the differences in death rates for lung cancer between those who were screened annually with low-dose helical (or spiral) CT versus the conventional chest X-ray. The study was published in the June 29th online edition of the New England Journal of Medicine. Dr. Denise R. Aberle, a principal investigator for the NLST and a researcher with UCLA’s Jonsson Comprehensive Cancer Center, said the publication of the study offers further definitive evidence of a significant mortality benefit from CT screening. “These findings confirm that low dose CT screening can decrease deaths from lung cancer, which is expected to kill more than 150,000 Americans this year alone,” said Aberle, who serves as vice chair for research in the Department of Radiological Sciences. “This study also will provide us with a road map for public policy development in terms of lung cancer screening in the years to come.” Aberle also commented that while the study cannot answer all the questions regarding implementation, “the NLST data can be used to develop mathematical models to determine how long screening should be performed and how often” and “can be used to determine whether other groups at risk of lung cancer,

such as light smokers, those with family histories of lung cancer or individuals with lung diseases like emphysema, would benefit from screening with spiral CT scanning.” CT technology in the medical field can be traced back to the early 1900s with Italian radiologist Alessandro Vallebona’s method for representing a single slice of the body on the radiographic film known as tomography. It is based on projective geometry—“moving synchronously and in opposite directions the X-ray tube and the film, which are connected together by a rod whose pivot point is the focus; the image created by the points on the focal plane appears sharper, while the images of the other points annihilate as noise. In the late 1970s, “minicomputers” and of the transverse axial scanning method developed by Godfrey Hounsfield and Allan McLeod Cormack moved the technology to “computed” tomography. This improved method took 180 separate readings every 1° with each scan taking a little more than five minutes. A large computer then reconstructs the images using algebraic equations…just like my tenth-grade math teacher warned me. While its success in the medical community is credited with saving countless lives, its benefits in the non-destructive technology field are also well established. Gain a better understanding of the rules of X-ray micro CT, not only opens the door to production cost savings and productivity improvement, but also knowing when to break them can provide even further process flexibility in this month’s feature article, “The Rules of X-Ray Micro CT (and When to Break Them),” by Andrew Ramsey.

NDT Industry Survey Points to Job Growth ARLINGTON, MA—In a recent survey by nondestructive testing (NDT) networking company PQNDT, the company asked a series of supplemental questions about layoffs and unemployment in the NDT industry. Overall, 7.5% of those surveyed had lost their jobs in the previous 12 months. The rate remained below the national unemployment rate, which hovered around 10% for much of the year, and is still above 9%. PQNDT gathered its data in 2010, while the country was still in recession. Of those laid off, most (70%) had found new jobs, and most of those found new employment fairly quickly (82% within four months). During the first half of 2011, there was a jump in the number of contract NDT

assignments. This is an indication of an increasing workload, tempered with caution about hiring permanent, full-time employees. That trend is now shifting over to more companies looking to hire for full-time permanent NDT positions, as the economic recovery begins to take more solid hold, according to the survey.

NDT Systems Celebrates 40th Year with Move to New Facility HUNTINGTON BEACH, CA— NDT Systems Inc. has relocated to a cus-

tomized facility three times the size and blocks away from its former facility in Huntington Beach, CA. The move coincides with NDT’s 40th year in business. NDT Systems was incorporated April 28, 1971, by Founder Ron Basko, a wellknown figure in the American Society for Non-Destructive Testing (ASNT), and credited with many innovations in the field. From the start, the company’s charter has been to develop, manufacture and market a comprehensive line of ultrasonic transducers and imaging devices. After 18 years of growth, the company was acquired by E.I. DuPont in 1989. DuPont sold the business in 1993 to a private investor involved with medical imaging. In 2000, the business was reacquired by Greg Smith, an engineer, inventor and long-time employee of the company. As the new president and CEO, Smith renewed NDT Systems’ com-

mitment to lead the field by improving and expanding the company’s line of non-destructive testing instruments and technology. Having outgrown its previous building, the roomier new facility creates an environment designed to stimulate and accommodate continued growth. Visitors are welcomed by an artistically designed and inviting reception area. A 700-square-foot meeting room is equipped for video conferencing and Internet access and the entire facility is wired as a proprietary Wi-Fi hot spot, providing building-wide access to locally hosted online sales and training tools. Office space has increased 2,000 square feet and manufacturing floor space has doubled. Because of the high-tech nature of the industry, and in response to the critical requirements of its customers, the company is under contract to earn ISO certification for the new building and its personnel.

with price points low enough to make it competitive with other techniques, X-ray micro CT is ready for the metrology mainstream. Better understanding the rules of X-ray micro CT not only opens the door to production cost savings and productivity improvement, but also knowing when to break them can provide even further process flexibility. Claims are made that CT is only appropriate for light metals, plastics or objects of limited size, when the reality is that such limitations may belong only to those making the claims. Better understanding the rules of CT certainly provides a better basis for what is possible with this technology.

The Basics X-rays are at the short end of the electromagnetic spectrum with an average wavelength between 10 -8 and 10 -12 meters, around the size of water molecules, compared to radio waves with wavelengths that could span a soccer field. There are no radioactive sources in X-ray micro CT; rather electrons are produced from a hot filament similar to a light bulb and accelerated at high voltage, creating a beam of electrons reaching speeds up to 80 percent of the speed of light. The electron beam is focused by a magnetic lens onto a metal target, producing a spot typically between 1-5 μm in diameter. The sudden deceleration of the charged electrons when they hit the metal target produces 99.03 percent heat and 0.7 percent X-rays. These X-rays emanate from the region where the electron beam hits the target. The size of this www.ndtmag.com

A minifocus source (around 1 mm) allows no magnification, whereas a microfocus source (1-5 μ) can be magnified to produce higher-resolution images. Source: Nikon Metrology Inc.

spot is referred to as the X-ray spot size. In general, the higher the voltage applied, the more power is in the beam, and consequently, more power is transferred to the target. The more power on the target, the larger the X-ray spot size and the more X-ray power produced. X-rays travel in a straight line, through the object being inspected, and onto a detector. The object will absorb some of the X-rays (denser objects absorbing more), leaving only a portion to reach the detector. At low X-ray energies (<60kV), www.ndtmag.com

differences of absorption along the X-ray path to the detector are detected and shown as a shadow image. At higher X-ray energies (60-225kV), absorption and scatter occurs. This scatter generally reduces contrast in the image. With X-ray energies above 225kV, scatter becomes an increasing problem for certain detectors. Above 225kV, scatter can be rejected from the detected signal by a linear detector, although throughput decreases (fewer images per hour). And at greater than 300-400kV, scatter is the

dominant contrast mechanism, i.e. more X-rays leave the beam from scatter than from absorption. Amorphous silicon flat-panel detectors have a fluorescent screen that converts the X-ray energy into light to form an image on an array of light-sensitive diodes. Electronics allow this image to be read by a computer. These panels can have pixel sizes over a wide range and sensitivities up to 16 bits (64k grey levels). The sensitivity of the detector relates, in part, to the size of the X-ray source. A lot of typical high-power X-rays sources are minifocus, in the range of 1 mm across. This limits the resolution of images to that of the detector; a very fine detector is needed to get high resolution and no magnification is possible. Microfocus means the size of the X-ray source is only a few microns across (1 micron or 1μm is 1/1000th of one millimeter). With a microfocus source, a standard detector can be used and geometric magnification can be used to gain a higher-resolution image.

TECH TIPS ● There are no radioactive sources in X-ray micro CT. ● CT combines the penetrating power of X-rays and the ever-increasing dataprocessing power of the computer. ● The metrology applications involving X-ray micro CT are varied and growing.

Internal features will be easily visible and usable. This allows us to zoom in and see more detail. And if the feature being analyzed is near the center of the scan, or if the size of the feature is much larger than a single pixel, then the number of projections can be reduced to speed up the scan. • Rule 2: Minimize the noise in each projection image If time is pressing, reducing the noise in the black and white reference images will reduce the noise significantly without greatly increasing the length of the whole scan. • Rule 4: Always take projections over 360 degrees If the object has a very long path that is difficult to penetrate but is narrow so that the lack of penetration only occupies a few projections (< 10-12), then these projections can be replaced with a corrected image with the sample not present. This adds no attenuation and so doesn’t affect the reconstruction. It is advisable to take some extra projections to compensate. • Rule 5: Use the whole dynamic range of the detector When inspecting very low density specimens, very low energy X-rays are used to give good contrast in the images. To fill the dynamic range requires long exposures. Halving the exposure only loses one bit of information but saves a lot of time The rules of CT come out of the theory of CT reconstruction. Following the rules means you will most likely get the best-quality CT data. But sometimes breaking the rules can save you lots of time without compromising image quality too much.

Thermo OF TURBINE Until recently, thermography was limited to a secondary, qualitative role in airfoil QA. However, advances in the technology have given rise to thermographic QA systems that are capable of replacing traditional technologies. By Steven M. Shepard, Ph.D.

T

The modern gas turbine airfoil is a marvel of modern engineering, material and manufacturing m mode sscience. Both airborne and land-based blades and scienc must operate under extreme thermal and v vanes mechanical stresses in the hot section of the engine, m mech and must be manufactured to the most exacting a m tolerances. Manufacture of a turbine airfoil is a multistep process that typically involves casting, coating and machining operations. The airfoils are formed by an investment casting process, where ceramic cores form a labyrinthine network of cooling channels in the mold. Once cast, cooling holes are then machined into the airfoil surfaces followed by application of a Thermal Barrier Coating (TBC). The safety-critical nature of an aircraft turbine or the dire economic consequences of a powerplant outage make quality assurance (QA) a primary concern for the entire supply chain, since inspections must be performed at every stage of the manufacturing process. Each stage presents unique challenges. For example, in the casting process, the ceramic cores may shift from their intended positions, or core residue may become embedded in the cooling channels. In the coating process, TBC thickness and adhesion to the metal must be confirmed. In machining, cooling holes may be formed incorrectly or become blocked by

core debris. At present, each of these challenges is addressed by a separate inspection technology, making the QA process a complex matrix of inspections that are performed serially, involving a variety of equipment, personnel and procedures. The net result is time-consuming and expensive. The serial application of different inspection methods and the laborious nature of some techniques can create significant logjams in production throughput. For example, the inspection of airfoils for blocked cooling holes is required for every blade in an aircraft engine. Each blade may have hundreds of tiny cooling holes. Currently, the standard inspection methods in the industry are pin-gauge testing, where an inspector manually inserts a fine wire into each hole, or alternately, a flow test, where a fluid is forced through the blade and an inspector visually observes the

spray pattern for anomalies. The pin test is labor intensive and prone to operator fatigue, and both methods are subjective.

Enter Thermography Since any object at a temperature greater than absolute zero generates infrared (IR) radiation, the IR image of an object at equilibrium with its surroundings is a static map of its surface temperature and emissivity. Commercially available IR cameras are capable of measuring the temperature of a surface, based on its radiative output, with sensitivities well below 0.1 C°. This ability to perform remote temperature measurement is widely used in predictive and preventative maintenance, where the equilibrium temperature of an object indicates www.ndtmag.com

its performance. However, if the object is heating or cooling in response to a deliberate excitation, the changes in the surface temperature measured by an IR camera can be mathematically interpreted to provide an image of the subsurface structure of the part that is comparable to an ultrasonic C-scan or radiograph. In this configuration, typically referred to as active thermography, various methods of excitation and signal processing can be used to accommodate a wide variety of materials and applications. The potential of thermography for non-contact, single-side, wide-area Nondestructive Testing (NDT) has been widely recognized since the introduction of the first IR cameras in the late 1960s. Although early efforts in thermography

were largely qualitative, and highly dependent on subjective interpretation of image results, modern thermography systems are widely used in manufacturing and in-service applications in the aerospace, power generation and automotive industries. Applications range from inspection of solar cell arrays in space satellites to QA of composite aircraft structures.

Active Thermography of Turbine Airfoils In the case of turbine airfoil QA, several forms of active thermography provide alternatives to the standard test methods. In fact, the entire suite of airfoil inspections can be performed using thermography. Until recently, thermography was limited to a secondary, qualitative role in airfoil QA. However, advances in the technology have given rise to thermographic QA systems that are capable of

replacing traditional technologies. Systems have generally been dedicated to a particular inspection, however, there has been a recent trend toward more comprehensive systems that perform several inspections. Leading companies in the field, including General Electric, Pratt & Whitney, Rolls-Royce and Siemens Westinghouse have added thermography to their palette of inspection tools. Flash Thermography is widely used in both coating and casting inspections. The airfoil surface is heated with a pulse of light lasting a few milliseconds. As heat from the surface diffuses into the metal, the surface cools in a predictable manner. However, the presence of an interface between materials (e.g. coating–metal, metal–air), flaws (e.g. unbonds or delamination) or internal structure (e.g. channel walls, turbulators, pedestals) disrupts the normal cooling behavior. The thermographic signal reconstruction (TSR) method is widely used to recover details of the internal structure, and allowing measurement of TBC or airfoil wall thickness with a degree of accuracy that is comparable to UT or eddy current methods.

phy have historically been used for qualitative inspection of flow through cooling passages and holes. In the simplest implementation, the operator views the IR image as a hot or cold fluid (typically water or air) is forced through the internal cooling channels. Blockages appear as discontinuities in the surface temperature along the channel, although partial blockages may be difficult to detect reliably. A new generation of flow ther-

mography systems provides far greater sensitivity and reliability for both channel and hole blockage. These systems can be fully automated and are gradually replacing manual pin test methods. Although Vibrothermography was originally discovered in the late 1970s, it has only recently come into its own as an NDT method that is particularly well-suited to detection of cracks in airfoils. Unlike other active thermography techniques where the entire component is heated or cooled, vibrothermography injects high-energy acoustic energy, typically in the 10-40 kHz range, into the part using an ultrasonic horn. Heating only occurs at a closed crack due to the rubbing action of the crack faces. Extremely small cracks can be detected in a few seconds, making the technique an attractive alternative to penetrant methods. Thermography offers a number of advantages when compared to traditional airfoil inspection methods. It is relatively fast (most inspections can be performed in a few seconds), automation-friendly and does not require contact or surface preparation of the part. It also provides an assessment of heat transfer performance, which is the essential function of the airfoil, while ultrasound, radiography and manual blockage detection provide only structural information. Looking toward the future, thermography shows great promise for inspection of the next generation of advanced turbine components, which are based on ceramic matrix composites (CMC). Active thermography presents several advantages over other conventional NDT methods such as ultrasound and X-ray for applications including porosity and wall thickness measurement, and detection of density variations and foreign object debris (FOD). In large part, this is due to the non-contact, non-invasive and curvature tolerant attributes of active thermography in conjunction with advances made in physics-based signal processing and material characterization.

Integrating Leak Assembly and Test The right leak testing method will help avoid the unnecessary costs of adding material and labor to fix defective production components. By Jacques Hoffmann In many automotive manufacturing scenarios, there are considerable advantages to focusing on th in-process testing as opposed to end-of-line testin ing. As a part or assembly is built, material and in labor costs are constantly added. The total value la of a production component is usually a function o of its percentage-completion and includes both labor and material costs. If one integrates testing throughout an assembly, one can avoid the costs of adding material and labor to defective production components. These are a few examples of how costs for rework and scrap can be avoided by in-process leak testing:

• Leak testing following ultrasonic welding of two plastic housings. • Leak testing following spin-riveting of a cover to a pump housing. • Leak testing after the insertion of an “O” ring or other seal.

Defective Parts or Defective Tests? The inability to differentiate good parts from defective parts may be due to faulty testing methods, which in turn are usually the result of inadequate understanding of real testing requirements. In leak testing, there are often problems with seal creep or fixtures that are not rigid enough.

Start by Selecting the Right Test Method There are various methods that one might choose from—simple pressure decay testing, differential pressure decay testing; helium mass spectrometer testing; and mass flow leak testing. Let’s look at each option.

Pressure Decay Testing The lowest cost method, pressure decay testing, actually has lower initial costs for fixtures, but may in fact be more costly due to longer test cycle times (pressure measurements required at the beginning and end of a known time interval). This method is especially vulnerable to outside interference, such as changes in ambient temperature, drafts, test-part deformity and seal creep.

Differential Pressure Decay Testing

There are various leak-testing methods that one might choose and a host of systems to get the job done, including an oil cooler assembly and test system (pictured). Source: InterTech Development Company 16 NDT ● AUGUST 2011

Differential pressure decay testing methods are superior to simple pressure decay testing, but are similarly inadequate for testing parts where temperature compensation is an issue. Both pressure decay and differential pressure decay test methods involve increased cycle times compared to other dry air test methods.

Helium Testing High cost helium testing, especially costly in the current context of rapidly rising helium prices worldwww.ndtmag.com www ndtmag com

wide, is usually justified in air conditioning and similar applications where potentially hazardous gas leaks less than 10-3 sccs need to be detected. Additionally, these instruments typically require more maintenance than other leak testing systems.

Mass Flow Leak Testing In most applications requiring detection of low leak rates, the lower cost mass flow testing method using customized, leak test capable, hi-resolution sensors is actually preferable, since it has the shortest possible testing times, can readily compensate for temperature and, overall, delivers the best accuracy, even in applications where testing is required at 0.05 sccm or less. The larger the part volume, the better mass flow test methods are when compared to pressure leak testing methods.

The Importance of Fixture Design The jigs and fixtures used in assembling an automotive product often have www.ndtmag.com

different and frequently contradictory requirements than those needed for accurate leak testing. That’s why upfront consideration of fixture design is usually required and tends to pay dividends in terms of accuracy and cost savings in the long term. And why off-the-shelf fixtures are almost always inadequate. For example, the physical dislocation of seals between the testing instrument and the component being tested, called seal creep, will compromise all methods of leak testing. Excessive clamping force on system joints can often mask leaks. Thus, expert fixture designs for dry air leak testing have several factors that they are managing: the part cannot have any creep or motion, it must be stationery; the part cannot be crushed or damaged; and the fixture design cannot mask leaks. Often a part being tested needs to be in the true car position, such as automotive valves. In some instances, assembly and test fixture designs must simulate the parts to

which parts are to be joined. While leak testing a transmission casting you would try to mimic the paper gaskets that will be in use in the field, as opposed to actually using paper gaskets since these wouldn’t hold up during the testing process. Fixture design is often mediated by how completely the overall assembly and test operation is automated, including specific testing stations. In manual systems, the sealing and fixturing may be more difficult because of ergonomic issues. Clearance for loading and unloading may be an issue. Poka-yoke considerations (a Japanese term meaning mistakeproofing) are such that often a fixture design will anticipate human errors of placing wrong parts in the testing stations. A poka-yoke informed fixture design will make sure that only parts with the correct dimensions will be tested. Since fixture design can make or break your assembly and test solution, it is generally advisable to enlist only test-

Specify Customized Software for your Data Highway Testing experts know that there are no one-size-fits-all generic testing solutions. Taking short cuts by selecting the lowest cost instrument from the shelf and placing it into assemblies rarely achieves gage R&R in acceptable ranges because the test sensors and software programming are not well-matched to application requirements. In most cases, custom software for test-intensive assemblies is actually less expensive than a generic off-the-shelf application because it is designed to meet real business needs and does not encum-

ber users with the costs for program features and functionality that is not actually required. Moreover, many general applications are not especially easy to use, or do not reflect the real data handling requirements of the application. Most test applications require software that works in real-time, which is usually not the case with off-the-shelf packages. It is important to have the means to view real time traces of a test instrumentation transducers’ performance, as opposed to simple test cycle times. Slower and less detailed applications do not process data quickly enough to provide for meaningful test control and/or test method calibrations. If the required data analysis is more complicated than generating a simple line graph, the off-the-shelf software packages that are commonly used similarly fall short.

R&R percentages based on the number of trials performed. How networks are built is also important in fully integrating testing into assembly operations. When there are steep requirements for testing, there is inherently a lot of data that typically has to be processed and also sent to a plantwide network. BUS compatibilities need to be considered.

fying business goals as to how the data and information garnered during testing will be used, not just in initial production, but also during the entire lifecycle of the product being produced in the assembly and test operation. This is of growing importance to automotive companies that now want processes to attach data to products from cradle-to-grave to assist with recalls or reducing time-to-market in new product development cycles. For instance, a leak detector can be interfaced with a bar code scanner and the customer data highway to provide a seamless f low of data.

Insist on Guaranteed Gauge R&R A tell-tale sign of a less than optimal assembly and test operation is one where the machine builder defines testing gauge R&R in terms of those proffered by the manufacturers of the test instruments.

Gauge R&R of the entire assembly and test solution is what counts, and this is what must be guaranteed to users of the test-centric assembly and test solution. This explains why the most savvy machine builders around the world are now incorporating applications engineers with a sole focus on testing into their project development teams. The improvements to be expected from a test-centric assembly approach are not trivial. Leak and functional test cycle times can be decreased 25–70% in the best-in-class examples and yields increased proportionally.

Laser Ultrasonics THE NEXT BIG NONDESTRUCTIVE INSPECTION TECHNOLOGY? A Frost & Sullivan Market Insight By Nikhil Jain

L

Laser ultrasonic testing (LUT) is a non-contact, nondestructive inspection technology that that nonde to generate and detect ultrasonic waves uses lasers la in the component under test. Laser ultrasonics may quite be the buzz word in nondestructive testnot qu ing (NDT) yet, but a handful of industries have rec(N ognized its benefits and have implemented a laser ultrasonic system to good effect. This article will provide a brief description of the technology and its applications, and analyze whether laser ultrasonics has the potential of becoming a standard technology in industrial inspection applications.

A Brief History: Origin of Laser Ultrasonics for Industrial Applications In theory, laser ultrasonics started with the development of lasers. Generation of ultrasonic waves was one of the first applications of lasers. However, detection of these waves posed the biggest challenge for its adoption in industrial applications. In the early 1980s, Krautkramer, now a part

of GE Measurement and Control Solutions, began the development of laser ultrasonics for industrial applications. It was unsuccessful as the technology had not advanced, yet, to a level that could permit practical cost effective solutions. However, Krautkramer can be credited with being the first company to venture into the commercialization of laser ultrasonics, which, until then, remained a research topic in universities and R&D centers. In late 1980s, the Industrial Materials Institute (IMI) of the National Research Council of Canada (NRC) began a large scale program in laser ultrasonics with Dr. Jean Pierre Monchalin, widely considered as the single most knowledgeable expert in this field, at the helm. This group was relatively successful in designing a cost effective system. During this time, Lockheed Martin also started development of laser ultrasonic systems for aircraft composite component inspection. The company recognized, as early as the 80s, that composite materials had a critical role to play in the future of aircraft design and construction. Although these landmarks did not materialize into commercial products being sold at a large scale, it made the industry realize the potential and advantages of laser ultrasonics. The actual commercialization of laser ultrasonics started in the 1990s, with several companies attempting to gain a foothold in a market that was still considered nascent and the technology still immature. In the late 1990s, Tecnar Automation licensed its laser ultrasonic technology for wall thickness measurement of seamless steel tubes from NRC, which was developed in collaboration with Timken Steel. This solution for wall thickness measurement of seamless steel tubes is considered to be the single biggest success of laser ultrasonics. Tecnar Automation is the sole licensee of this technology and sells this system to steel tube mills globally, with considerable success.

made, they can be made immediately. In effect, the laser ultrasonic system is performing in-line inspection. This is the biggest benefit of a laser ultrasonic test system in the wall thickness measurement of seamless steel tubes. According to Dr. Marc Choquet, VP Laser NDE at Tecnar Automation, “The only other technique for in-line inspection on seamless steel tubes was gamma ray technology which had severe limitations.” In gamma ray inspection—apart from harmful radiations—restrictions on wall thickness range and position and shape of the tube limited the accuracy and efficiency of inspection. “Well, now we go a little bit into the realm of possible,” says Dr. Marvin Klein, Manager, Laser Ultrasonics Products Group at Intelligent Optical Systems. “Each person you ask is going to give you a different answer on the future applications for laser ultrasonics, but for me automated weld inspection is a very promising application.”

In addition to the aforementioned applications, research is also being conducted in a number of new areas, such as inspection of adhesives in the automotive body assembly, detection of lap joint corrosion in an aluminum airframe and determination of elastic constants on ceramics and ceramic-metal composites up to 1,800°C (3,300°F). There are no industrially installed systems for these applications, but there is significant potential in some of them.

Intelligent Optical Systems has researched the automated weld inspection market for the past five years and has developed a system for this application. Dr. Klein says, “Our system is particularly good for laser welds as they have generally very high requirements of integrity and it is a fully automated process.”

Is There a Market for Laser Ultrasonics? Although industrial application of laser ultrasonics has been around for over a decade, it is still a relative unknown amongst most end-users. As is the case with any new NDT technology, acceptance continues to remain a hindrance. The two major applications of laser ultrasonics target the aerospace industry and steel mills, which are considered conservative when it comes to new technology adoption.

Dr. Choquet says, “It takes a long track record before the technology is accepted in aerospace industries and steel mills without any questions. So we have probably passed the introduction phase, in that it is no longer a new technology but it is still not a standard technology.” One of the major challenges laser ultrasonic technology faces is price. Industrial laser ultrasonic systems range from $500,000 to $2 million, although R&D systems are less expensive. This is a major setback for end-users with limited budgets. Although, these prices may seem quite high, when measured against cost savings they can often be justified. This is another challenge for the laser ultrasonic equipment manufacturers; educating end-users on the actual savings that could be achieved by installing a laser ultrasonic system as apposed to other inspection technologies. Despite these challenges and slow acceptance of this technology, several experts strongly believe that it has the potential to become the standard technology in certain applications. According to Dr. Klein, “One of the ways of assessing market acceptance is by the number of enquiries, and for us that number has gone up considerably. In some enquiries, people are already aware of the technology.” Dr. Choquet concurs with that statement, “There has been an increase in our sales for the seamless steel tube inspection system.”

barriers to this inspection technique, however, end-user and industry mindset will need to change for this technology to become standardized. NDT Nikhil Jain is Research Associate for Frost & Sullivan’s Measurement & Instrumentation group. Frost

Conclusion There are undoubtedly clear advantages to laser ultrasonics in seamless steel tube inspection and composite component inspection applications. To put things in perspective, it has all the benefits of conventional ultrasonic testing, such as accuracy and speed, in addition to being non-contact, flexible and fully automated. Although steel mills and aerospace industries have been traditionally conservative in embracing new technologies, they are gradually realizing the effectiveness of this technology. Laser Ultrasonics is expected to eventually become a standard technology for these applications with industry experts estimating anywhere in the region of 3-5 years for large scale market adoption. There are no specific technology www.ndtmag.com

HOW TO MAKE YOUR MACHINE WORK SMARTER Automate my fixture and part set-ups. ✔ Verify the integrity of the tool in the spindle. ✔ ■ Measure and compensate cutter length and diameter at working RPM. ✔ ■ Confirm my machine’s calibration status. ✔ ■ Stop my machine in milliseconds in case of a crash. ✔ ■ Measure critical part dimensions and geometries without moving the part to a CMM. ✔ ■ ■

Only one gaging company can supply a cost-efficient suite of spindle touch probes, laser tool setters, on-machine measurement and verification software, crash sensor, tool, machine and process monitoring technology, then take total responsibility for integrating the components and ensuring your successful application — MARPOSS.
