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.”

Tooling to Match Composite Production

It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”

Solutions for Difficult Machining

The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.

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.

What’s the Connection?

A lot of attention is paid to the “business end” of CNC toolholders–the part that actually holds the tool.

Tooling and Workholding Systems

“We are developing solutions for power workholding such as hydraulic swing clamps and block clamps, because the real estate on a fixture is so valuable,” says Jason Betz, product specialist for Carr Lane Roemheld (St. Louis). “This pushes the use of smaller workholding components as much as possible because the more parts on the fixture the greater the productivity.”

New Uses of Noncontact Metrology in Aerospace

Aircraft manufacturers are finding noncontact metrology ever more useful. Its inherent high throughput and decreasing cost is complementing the industry’s ramp-up to meet the world’s appetite for more airplanes.

Conductive Thermoplastics for 3D Printing

As inventive and imaginative as 3D printer technology is, so are the materials that R&D labs have come up with to build parts, including conductive thermoplastics.

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.
