Change-up Pitch: From Metal to Plastic

Even though it’s been around since the 1950s, when engineering-grade resins were first introduced, many manufacturers still are not familiar with the many benefits that metal-to-plastic conversion provides.

Creating New Value at Toyota

I traveled to Toyota headquarters in Japan with Jeff Liker for a research project. We wanted to learn more about the engineering and collaboration that created the Toyota New Global Architecture (TNGA), the strategy and innovation behind hydrogen vehicles, and how they had adapted and improved their development system to meet the increasing demands of the ultra-competitive global auto industry.

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.

Auto Industry Faces Short- and Long-Term Challenges

Sales of cars and light trucks plummeted during the Great Recession and General Motors Co. and Chrysler emerged from government-back bankruptcies in 2009. Since then, total industry deliveries have surged, hitting a record 17.47 million in 2015, according to Autodata Corp.

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.”

Geometry Lesson Teaches Corvette How to Lighten Up

It’s been almost two decades since the C5 Corvette hit the streets with its groundbreaking chassis built around hydroformed steel bumper-to-bumper frame rails. The technology gave engineers a chance to create components that were both lighter and stiffer than traditional stamped and welded assemblies.

Hard Hips

The challenge of machining hip replacement implants out of cobalt chrome

Quality Inspection and the CAD Connection

Modern manufacturing is rapidly adopting model-based definition (MBD). When employing an MBD strategy, the CAD model becomes more than the nominal to which all parts are measured and inspected against. MBD keeps the all-important digital thread intact—from design to manufacturing to inspection and quality reporting.
