Optical Comparators Adapt and Grow

Beware predictions of the demise of any technology. If the early 1920s saw the dawn of the optical comparator, there has been much speculation about its sunset. That was especially true when vision systems started hitting their stride a few years ago. Many could see optical comparators were superfluous with the use of vision systems. Many thought the sunset of optical comparators was imminent. Many were wrong. Why?

UNCC’s Hands-On Approach to Manufacturing Research

Starting this month, TechFront has a new format that spotlights manufacturing research programs at key universities, followed by summaries of recent research in SME’s Journal of Manufacturing Systems, Journal of Manufacturing Processes and Manufacturing Letters, all published by Elsevier Ltd.

The Quest for Safer 3D Printing Materials

When Desktop Metal introduced its “office-friendly” Studio metal prototype printer earlier this year, the company renewed attention on the issue of safer materials for binder jetting, an additive manufacturing method.

Cold Sintering Process Saves Energy, Material

Researchers at Penn State University (University Park, PA) have devised a novel method for sintering, a widely used manufacturing process for powdered materials. The new process, which uses much less time and energy than current approaches, could have global implications on manufacturing and energy savings and pave the way for new discoveries.

Lean Manufacturing and Industry 4.0

At UGN, one of our core operating principles is sustainability. That means minimizing waste to improve efficiency, add value, and refine the manufacturing process for our automotive products when and where we can.

Additive Grows and Has Growing Pains

Additive manufacturing is both growing and coping with growing pains. Companies “have to find ways to streamline” polishing and other finishing processes of 3D printed parts, industry consultant Terry Wohlers said today during a speech at RAPID + TCT.

Fast, Flexible Fixturing

Secure, accurate workholding sets the stage for consistent machining productivity. Depending on the parts and processes involved, workholding can be as simple and temporary as a plain vise or clamp or as complex and permanent as a machined and fabricated fixture that is custom-designed to hold a unique part.
