There’s nothing mysterious about the need for calibration. As Michael Wilm, business manager for calibration products, Renishaw Inc., West Dundee, Illinois, put it: “When you get gas for your car, you count on the pump being calibrated. That’s why we calibrate machine tools. If you don’t calibrate a machine tool you have no idea it’s going to give you reliable service for manufacturing your product.”

In the manufacturing industry, the importance of metrology, or the science of measurement, is often underestimated. However, inspection is critical for ensuring products work and operate safely.

Innovate, Integrate, Collaborate are more than just marketing keywords. A number of metrology and software companies I visited at IMTS are putting their development dollars to work in these areas and showing off the results.

Considered by many to be the “Father of Quality Management,” Dr. Joseph M. Juran is recognized as the man who added a human dimension to quality, expanding it from its statistical origins to a broader management science.

Beware predictions of the demise of any technology. If the early 1920s saw the dawn of the optical comparator, there has been much speculation about its sunset. That was especially true when vision systems started hitting their stride a few years ago. Many could see optical comparators were superfluous with the use of vision systems. Many thought the sunset of optical comparators was imminent. Many were wrong. Why?

While high-end metrology devices like advanced laser scanners or precision CMMs garner a lot of attention, it is hard to imagine any industrial setting without the presence of work-a-day hand-held, contact metrology tools such as calipers or micrometers. That is what Justin Frazzini, quality manager for A.A. Jansson (Waterford, MI), retailer and calibration and repair service provider, observes in his practice.

The industrial world is continuing its adoption of Geometric Dimensioning and Tolerancing (GD&T), the advanced tolerancing methodology. The symbolic language is intended to be both more precise while providing more latitude in allowable variations, replacing the simpler method of adding tolerances to each dimension.

“Five years ago, our fit and finish was below average,” said Dr. Raj Kawlra, director of dimensional strategy and management of Chrysler Group (Auburn Hills, MI). “To be the future world-leaders, we knew that we had to focus on all aspects of quality … vehicles that look good, feel good, sound good, and are reliable.”

Off-line programming software tools for CMMs allow manufacturers to increase measurement capacity and throughput by programming CMMs, probes, and fixtures before parts are made.

In this podcast, John Derry, senior application engineer at Promess, talks to SME Media contributing editor Michael Anderson about reducing complexity in assembly equipment. Derry discusses how assembly systems may become unnecessarily complex--and how that complexity can reduce quality and increase costs. Derry goes on to describe effective ways of addressing these issues and to reduce and even eliminate unnecessary complexity.
