I- space, the cradle and work reverse direction, the work is withdrawn and indexing takes place. The work head moves forward and the sequence of motions is repeated until every tooth has been cut. The machine stops automatically when the work is finished. The special high production cams produce the same sequence of motions, except that the rate of roll varies so that the blades remove equal amounts of stock during all portions of the gen erating roll. When the straight infeed path is employed, the rolling motion of the gear and cradle is locked and the tooth space is cut by a depth feed of the work directly into the cutter. After each tooth space is cut the work is withdrawn and the gear blank is indexed to the next tooth space. This sequence of motion is repeated until the gear is completed.
