Every so often, I like to present a few Web sites I’ve come across that are of special interest to CNC users. While some of the Web sites I mention have products to sell, they also have free information about CNC.
Short workpieces must be machined on turning centers on a regular basis, but lot sizes may not justify the use of a bar feeder or puller. In these cases, it is often helpful to machine more than one workpiece from a single piece of raw material.
Certain machine shop rules must never be broken. If they are, the results can be disastrous.
Mistakes made when running CNC machine tools will cause consequences. At best, the machine will not behave as expected.
Setup reduction has been a hot topic for several years. Everyone wants to reduce downtime between production runs, and companies go to great lengths to achieve this goal.

Aside from the fact that other columnists are addressing issues related to computer integrated manufacturing, I believe that a firm understanding of manual programming is of paramount importance to all CNC people.
