Theory. Cutting speed is the relative linear velocity between the tip of the cutting edge and the workpiece. It is a result of the product between the rotation speed of the milling cutter ( Spindle speed) and its circumference. C = 2 × π × r = π × d. V c = n × C. Important Note: The Diameter (d) should be the effective diameter and not ...Web
