Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
Milling cutters with insufficient feed tend to generate heat in the workpiece and tool life will be adversely effected. Starting Points. Although exact speeds and feeds can be calculated for a given operation, these values are starting points at which the cutter should operate successfully. The machine may need to be run a little faster or ...
