Calculating Surface Footage and RPM for Optimum Tool Life
Lately, I have found myself engaged in debates with younger people on how to properly calculate rpm from surface speed. The heart of our disagreement is centered on which diameter to use when converting surface speed to rpm. Also, I think much of the misconception comes from programming in constant surface footage.
My understanding of surface speed per minute is the measurement of the linear surface that travels past a given point with every revolution in one minute of time.
