Fast, Big and Easy: Trends in Metrology

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.

Interpreting the Language of GD&T in Metrology

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.

Programming CMMs

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.

New Metrology Culture Improving Chrysler Quality

“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.”

Advances in Hand-Held Metrology

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.

IMTS in Three Words: Innovate, Integrate, Collaborate

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.

Masters of Manufacturing: Joseph M. Juran

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.

Quality Scan: Thread Inspection: Your Application Matters

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.

3D Laser Gaging Ensures Flawless Engine Fasteners

In an automobile engine, seven types of screws out of approximately 70 are considered critical to achieving the engine’s specified design performance, despite high vibration and heat. The seven include bolts for the cylinder head, crankshaft, con rod, flywheel, and main bearing cap, as well as for the camshaft cap, camshaft sprocket and VCT.

3D-Printed Parts Restore Cars’ Glory

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.
