To profitably machine high-quality parts, many manufacturers follow a similar path, beginning with tool selection and application and then solving any problems that arise in a reactive way. However, research suggests that manufacturers should examine the entire machining process before cutting begins, focusing on eliminating rejected parts and unforeseen downtime.

Numerous toolmakers provide free programs that will automatically generate G code for a specific thread milling application. The programs vary in sophistication and in whether they are online-only or downloadable, but all are useful tools. Among the suppliers of these apps are Scientific Cutting Tools Inc., Simi Valley, Calif.; Guhring Inc., Brookfield, Wis.; and Kennametal Inc., Pittsburgh.

Scrap happens. By scrap, I mean parts that are out of tolerance and, therefore, useless. Unlike other by-products of the manufacturing process, such as chips, shavings and drops, you generate scrap only through mistakes. nnSo the challenge of reducing scrap comes down to preventing mistakes.

Swarf, which is the result of particles being removed when grinding hard or difficult-to-machine materials, tells a story.

Metal laser melting has made possible a number of groundbreaking developments in the medical field. One example is a 3D-printed bone drill that, unlike some traditionally manufactured drills, is designed not to damage tissue during surgery.

The boost in productivity that the latest cutting tools provide enables manufacturers to reduce the amount fracking companies pay for parts.

Until a couple of years ago, the Food and Drug Administration required a unique identifier on each distinct assembly of a medical device in human- and machine-readable forms. That rule has changed. Now, every individual component in an assembly must be marked as well. Traceability is becoming more and more prevalent, not only in the medical device sector but throughout manufacturing.

Trochoidal milling is a relatively new cutting strategy that involves the overlapping of circular toolpaths with linear movement. It is well-suited for difficult-to-machine materials and thin-walled components.

An item in the Look Ahead department of the August 2017 issue of Cutting Tool Engineering magazine features large-volume, high-accuracy robots.

Low-wattage lasers are faster, gentler and more eco-friendly than traditional parts-cleaning methods. So why aren't they more prevalent?
