Abstract
An improved method is provided for finish machining forged and/or rough-cut teeth (8) of a ring gear (40) by which a rotary tool such as a rotary carbide milling tool (24) is rotated about a rotational axis 'r' that projectionally intersects a bottom surface (12) of tooth (8) as it tracks along a predetermined tool path enabling the rotary tool to be in close proximity to sidewalls (14 and 14') of teeth (8) and thereby eliminating the practice of having to normalize the ring gear microstructure prior to machining teeth (8).
