Machining manifolds generates numerous burrs, and removing them is no simple task. Basin Precision Machining attempted a variety of deburring methods, including waterjet, kinetic energy and the thermal energy method (TEM).

In the August 2017 issue of Cutting Tool Engineering, Ask the Grinding Doc Columnist Jeffrey Badger, Ph.D., fields questions about spotting wheel loading, white sticking for hardened steel loading, and what causes barber pole marks during cylindrical-traverse grinding.

In the August 2017 issue of Cutting Tool Engineering, Shop Operations Columnist Tom Lipton challenges readers to take a good look at the venerable 4-jaw independent lathe chuck. "Many machinists may have never used one. Hopefully, my call to arms will change that, and a whole new world of workholding will open up to them."

A milestone in the 3D printing revolution is the appearance of CNC metalcutting machine tools incorporating additive-manufacturing capabilities. Manufacturers of the hybrid additive/subtractive systems tout their advantages over conventional machine tools, but the hybrids raise important issues that their builders and users must address.

Much of 2016 and 2017 has been a stressful roller coaster ride for our shop and me and my family as we have fought through a difficult economy—the worst in 30 years. Challenges remain, and business isn't completely wonderful again, but we have more optimism than a year ago, writes Keith Jennings, the Manager's Desk columnist for Cutting Tool Engineering magazine.

Since the time CTE Editor Alan Richter started covering manufacturing for CTE in 2000, industry professionals have frequently informed him that manufacturing jobs typically pay more than most other professions, such as sales and low-level, white-collar jobs. Furthermore, he was told, they provide a multiplier, or ripple, effect—in which one manufacturing job produces numerous other jobs.

Some machine tools are modified so much and so frequently it becomes a common practice. That's certainly the case with rotary transfer machines.

G2 Technologies has developed a customizable, automated 3D inspection system in response to a customer's need to inspect small electronic connectors. This niche is very specific, but impacts aerospace, automotive and other industries. The global market for the connectors industry is projected to reach $80.3 billion by 2022, according to G2.

The welDYNA laser scan head from SCANLAB America Inc. uses beam oscillation to improve both joining and cutting applications. Designed for multiple-kilowatt lasers of high beam quality, the scan head features a digital servocontrol and an integrated sensor system for real-time monitoring.

Sawing is one of the most common manufacturing processes in a machine shop. It is versatile, simple and reliable. Nonetheless, many young engineers and machinists are quite familiar with lasers and abrasive waterjets but have no knowledge of sawing.
