Machine Vision Inspection Speeds Up Automotive Lines

As machine vision technologies improve, providing more data more frequently, new uses for inspection during the manufacturing process are emerging. The automotive industry might represent the ultimate challenge to providers of machine vision equipment used in robotic guidance and material inspection.

Extrusion and Drawing Knowledge

Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.

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.

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.

Metrology Tools for Medical: A New Focus on Vision Systems

Metrology for medical devices needs to become more capable as those devices get more varied and complex. Manufacturers must inspect dental implants, coronary stents, orthopedic joints, and implanted electronic devices. Surgeons are increasingly using intricate, sometimes one-off, surgical tools. There is also a growing number of consumable items, such as hypodermic needles, made on rapid production lines. They all need ever more precise quality control.

Pilot Composites Workshop Wows Students

Carbon fiber is a magical material. That or similar comments were heard over and over from Roosevelt High School (Seattle) students attending a Composites 101 Workshop held at the National Resource Center for Materials Technology Education (MatEdU), a National Science Foundation Advanced Technological Education (ATE)-sponsored program at Edmonds Community College (Lynnwood, WA).
