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.

A hydraulic expansion toolholder that can be adjusted to have zero runout accuracy.

A wirelessly powered machining sensor system.

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.

Shop Operations: The manual lathe is the cornerstone of any machine shop because almost all shop workers find themselves working on one when they start. The manual lathe has been called the "king of machines," for good reason. Some can be enormous; you can bet that if you need a forklift and a ladder to put a tool bit in the machine, some fun is bound to happen.

When turning 2mm-dia. and smaller parts on a Swiss-style machine, it only makes sense that the radius on the tool should be equally tiny. After all, you can't cut a 0.5mm bone screw with a TNMG-431 insert—the tool's nose radius is nearly as big as the part.
