Charts & Calculators  Destiny Tool
Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill.

COMMON EQUATIONS FOR OPTIMAL PERFORMANCE
speed to the diameter of the tool, and the rotational speed of the machine spindle are explained. Inches per minute (IPM) is the standard for which feed is commonly measured. Feed is calculated by the number of cutting teeth in the end mill, multiplied by feed per tooth, multiplied by the revolutions per minute.
