Today, the productivity needed to be globally competitive requires ever increasing metal-removal rates during operations such as roughing and high-speed slotting. Process reliability is paramount, especially when working with difficult-to-machine materials.

PITTSBURGH — Stratasys Ltd. introduced a prototype of a 3D printing system that maintains low-volume output continuously as the company moves to expand its presence in industrial production.

Impossible Objects announced today the launch of Model One, its pilot 3D printing machine to revolutionize high-volume manufacturing and initial customer deployments with select Fortune 500 customers. The announcement took place at the RAPID+TCT 3D printing and additive manufacturing conference.

The pace of 3D printing adoption will accelerate, a General Electric Co. executive said during an address at RAPID + TCT today.

Toolholding for rotating round tools—end mills, drills, and taps—continues to evolve with innovative designs aimed at guaranteeing precision, security, and repeatability. As a result, suppliers of toolholding technology have made supporting the precision, security, and repeatability of shrink-fit, mechanical, and hydraulic toolholding the highest priority.

You don’t have to look too far to find tooling presetters that fit the machining requirements of just about any size shop. The value of off-line tool presetting—rather than stopping machine spindles to touch off tools as machines sit idle—continues to prove itself invaluable, especially to the smallest first-time user shops.

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

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.

Digital tool management systems, and the digital tool libraries that support them, are changing the way cutting tools, toolholders and workholding are assembled into tooling setups and used to machine parts

Advanced tool grinding technology, more capable and precise than ever, has meant new ground-breaking cutting tools, such as a variable geometry designs. Just as importantly, other machine tool providers need to offer automation and advanced in-process sensing to make proven tool grinding operations even more efficient.
