Abstract
A method and apparatus for cutting a pair of circular grooves in the side edges of the periphery of a circular disk such, for example, as the stator of an alternator. A milling cutter having axially spaced cutting elements along its periphery is positioned so that its axis is parallel to the axis of the disk. The cutter is moved toward the disk while being axially rotated, to cause the cutting elements to cut into the side edges of the periphery of the disk. The disk is then rotated one full turn to cause the cutting elements to cut the grooves.
