Milling Speed and Feed Calculator 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. In many milling operations the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.
