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.

The integration of additive and subtractive enables product designers to pursue product enhancements that could not be manufactured in any other process. At the same time, this combination is reducing the time it takes to prepare for parts production, including acquiring the necessary tooling.

Companies strategically adopt cutting-edge solutions to help solidify their position within a competitive marketplace. Years ago, blue light 3D scanning technology was implemented to help product development and alleviate coordinate measuring machine (CMM) bottlenecks.

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.

When first introduced in the late 1970s, cutting tool coatings—especially titanium nitride (TiN)—were embraced by tool manufacturers for their ability to extend tool life. As workforce materials have expanded from conventional ferrous and nonferrous metals to exotic alloys, composites, ceramics, and others, coatings have likewise progressed and, thanks to new formulations and deposition methods, are extending cutting tool capabilities as well as tool life.

Manufacturing Engineering asked thought leaders at five companies for their views on challenges and trends facing the metalworking industry.

Q&A with Chirayu Shah, Marketing Manager, HMI Software, Rockwell Automation

The nexus of cyber and physical security threats is the stuff of nightmares, and while manufacturers are waking up to it as a reality, experts worry that the awakening is happening too slowly.

PITTSBURGH—Doctors and scientists at Northwestern University have been working diligently for about seven years to bring new materials to clinics that handle plastic and reconstructive surgery, as well as transplants, Sue Jordan, chief resident in plastic and reconstructive surgery at Northwestern Memorial Hospital, told a crowd gathered to hear her speak today at the RAPID + TCT show.

Comau, Microsoft and ICONICS are debuting here at Hannover Messe the results of their work together to improve manufacturing production around the world, in terms of efficiency and total cost of ownership.
