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.

Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.

The first kilowatt-class fiber laser for material processing was introduced by IPG Photonics in early 2002. Since that time, the adoption of fiber lasers for production applications has grown at a rapid rate. Today, fiber lasers are becoming the choice for most major production laser applications as well as converting traditional welding and cutting processes to fiber laser technologies.

Moldmaking is making a comeback, with more reshoring to North America of mold-and-die manufacturing that left for the Far East and other low-cost manufacturing centers. With faster metalcutting through high-speed machining (HSM) and improved EDM techniques, mold-and-die shops are finding innovative ways to compete with manufacturing operations in traditionally low-cost labor markets.

Nesting is the process of arranging parts to be cut from sheets of metal or wood in the most efficient manner possible in order to maximize yield and speed the cutting process. By reducing scrap and accelerating the cutting process, fabricators are saving on material cost while running more jobs.

Not all threaded connections serve similar purposes.The load-carrying needs of an aerospace engine support bolt in a tension assembly greatly exceed those of a simple screw that fastens a cover plate to an electrical wall socket. International thread-acceptance documents and standards recognize this basic engineering fact, and incorporate different thread-inspection requirements into their verification standards.

In this exclusive interview with Manufacturing Engineering, Norbert Hanke president of Hexagon Metrology shared his views on a number of high level topics that illustrates where Hexagon Metrology – and the industry – is headed in the next few years.
