How to Overcome an Acc/Dec Limitation in High Speed Machining

A small pocket in a graphite workpiece limits productivity. Part of the expert’s response is to consider how a lower feed rate might actually be more productive—because the machine will spend more time at the programmed rate.

When Spindle Speed is a Constraint

Though it won’t replace high speed machining, Boeing sees “low speed machining” as a viable supplement to higher-rpm machines. Using new tools and techniques, a shop’s lower-rpm machining centers can realize much more of their potential productivity in milling aluminum aircraft parts.
