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.

Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.

Sometimes, too many choices can be a problem. That might be the case today for manufacturers of medical devices, who are facing a host of challenges and opportunities. Devices are small and getting smaller. Their complexity is increasing. End users are demanding tighter tolerances.

I’m among the first to dive into the latest manufacturing innovations and see how they can improve our customers’ operations. Yet, I’m also among the first to advise them to pause and ensure that the fundamentals of their manufacturing processes are in place before adding something new into the complex mix of functionality and desired outcomes.

PERFECT-3D might not appear to be an acronym, but it is, standing for Process Enabled Repeatability For Extended Life & Consistent Tools. PERFECT-3D’s process for 3D printing of ceramics for complex components resulted from the collaboration of its parent company, Renaissance Services Inc. (Fairborn, OH), with the US Department of Defense, a major investment casting company, a large chemical company, and an aircraft engine manufacturer.

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.

SAS Manufacturing LLC unveiled a new advanced machining facility for design, manufacturing, and assembly of aerospace components in Arvada, Colo.

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.
