The Milling Process – Definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round

Learn MoreThe Speeds and Feeds Calculator uses the following formulas: RPM = (12 * Surface Speed) / (PI * Tool Diameter) [revs/min] Feed Rate = RPM * Chip Load * Number of Teeth (Flutes) [in/min] Where PI is the constant (3.141592654).
