It’s the machine tool acronym you never bother to put into words: CNC. And much of the time it’s probably OK to view your “computer numerical control” as a black box doing magic. But if you’re struggling with high-speed machining, need better surface finishes or higher accuracy, have training and retention problems, or want a better handle on your production efficiency, the answer just might be the latest iterations of those three little letters.

The Ceratizit Group (Mamer, Luxembourg) acquired the Komet Group (Besigheim, Germany) on Oct. 12, 2017. The transaction is still subject to the approval of antitrust authorities.

Machine tool orders posted mixed results in November, slipping a bit on a monthly basis while recording a solid gain compared with a year earlier, according to a monthly report by the Association for Manufacturing Technology (McLean, VA).

May U.S. cutting tool consumption totaled $215.13 million, according to the U.S. Cutting Tool Institute (USCTI) and AMT—The Association For Manufacturing Technology.

From Boeing 787s to new Navy destroyers, fiber-reinforced composites are gaining in use. As production scales up, more-efficient manufacturing remains a focus. One key to that efficiency is tooling for composites. These molds and forms give the final shape to a part, and are often integral to their final curing.

Edge finishing is a relatively new term in manufacturing. It’s a new and deeper focus on what many used to call deburring, edge honing, edge preparation, edge prepping, burring, chamfering, or edge blending. Edge finishing goes beyond any of those definitions. Deburring, which is often considered wasted effort by managers, wrongly carries a negative connotation. In reality, deburring and edge-finishing processes add many benefits to parts—they create highly desirable edge quality—the quality most products need.

Workholding techniques using a magnetic field, a vacuum, or an adhesive can be effective alternatives to clamps. When these techniques are used, more part area is available for the cutting tools, thin parts can be held, and initial setup can be fast and simple. Plus, there is a potential for smoother surfaces and a shorter overall production cycle.

Raym-Co Inc., located in Farmington, Conn., is a job shop with a 37,000 ft2 (3,065 m2) facility and approximately 60 CNC machines.

New replaceable drill tip saves tooling costs and eliminates process steps

Sales figures don’t lie: indexable cutting tools—featuring removable cutting tips called inserts—are a smash hit with machine shops.
