When the time came to begin thinking about what to include in our latest special issue on high speed machining, I imagined an introductory article titled something like "High Speed Machining Comes of Age. " What was a relatively new idea several years ago is now much more widely known.
People who write about metalworking, including me, sometimes fail to choose their words carefully. They often speak of a "shortage" of skilled machinists, when in fact the problem is one of reduced supply.
Vibration is at the heart of a variety of common problems in machining holes. Mathematical analysis is helping to bring about a better understanding of hole-making processes...including how these vibrations behave, and what steps to take to bring them under control.
A watershed moment in spindle evolution? For the latest generation of high speed spindles used in milling, spindle makers look beyond traditional bearings.
