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.

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.

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.

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

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

Although laser welding is a well-established manufacturing solution, many sheetmetal fabricators have been hesitant to implement the process at their shop.

As both robots and lasers improve their capabilities, they prove to be even better partners in more applications

Larger titanium aircraft components are being manufactured faster with selective laser melting 3D printing technology from SLM Solutions NA Inc.

The demand for titanium components by the aerospace industry began as a whisper about 15 years ago and steadily grew to a sustained, raucous shout over the last five and likely won’t quiet for several more.
