Abstract
An involute external tooth profile is cut into the periphery of a gear blank by positioning a rotating milling cutter with its cutting path perpendicular to the plane of action of the desired base surface of revolution within the gear blank so as to penetrate the plane of action from the side thereof opposite to the base surface and with a predetermined line of intersection which generates the involute profile as the base surface rolls upon the plane of action. The rolling action causes the generating line to traverse the blank between its addendum surface and a depth sufficient to provide the desired length of active profile.
