Machining

The Machine Technology column for the January 2012 issue of Cutting Tool Engineering focuses on developing an understanding of the role of drawbar force.

Michael Deren covers the benefits of attending regional trade shows in his January 2012 Machinist's Corner column for Cutting Tool Engineering.

Strategic approaches maximize utilization when multitask machining.

In the olden days, riggers were the guys on the ground placing slings and chains around the object to be moved while the crane operator waited for their signals to begin lifting. Today, rigging in a small shop falls to the guys standing closest to the equipment when something needs to be moved.

Measuring or modeling the natural frequencies and mode shapes is a useful step in avoiding or eliminating vibration problems.

Manufacturers are using unattended horizontal machining cells to improve productivity and quality.

Many large corporations are well versed in total productive maintenance, but smaller companies are probably not. To learn more about the concept, I attended a 1-day seminar about TPM at a local technical college.
