COMMON EQUATIONS FOR OPTIMAL PERFORMANCE Too high of a speed or too light of a feed leads to reduction in tool life. Speed is measured in feet per minute and is referred to as cutting speed, surface speed, or peripheral speed. In the tables below, the relationship of peripheral speed to the diameter of the tool, and the rotational speed of the machine spindle are explained. Inches per minute ...
