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.

German auto supplier boosts use of 3D printing

One of the early applications for 3D printing/additive manufacturing (AM) was in the medical industry. As the machines and materials have improved, the use of these technologies expanded into almost every application. In medical, there are unique challenges as patient safety is paramount and government regulation and insurance issues structure what can and will be done.

The past 12–18 months have been more exciting than any similar period in the history of additive manufacturing (AM), more commonly known as 3D printing.
