Turning Speed and Feed Calculator

Turning is a common machining operation in which material is removed from a rotating workpiece by feeding a single-point cutting tool axially, along the side of the workpiece. The motion of the cut is specified through several parameters, beginning with the cutting speed and cutting feed, which are selected based upon the specific cutting operation, workpiece material, tool material, and other cutting parameters. The speed and feed calculator can be used to determine the spindle speed (RPM) and feed rate (IPM) for the specified cutting conditions and cut diameter. In some turning operations, the diameter of the workpiece will change so the spindle speed and cutting speed (SFM) must change as well. Typically, values are calculated for a single cut diameter and then either the spindle speed or cutting speed is held constant while the other varies. The calculator will also show the cut time for a given cut length.
