Abstract
A method for machining a part with gear teeth onto an unmachined part to form drive pinion gears is disclosed. A center bore is formed at one end of the part and receives a tool center to mount the part for machining. The center bore includes a plurality of lobes which are in point contact with the lathe center, allowing adjustment between the unmachined part and the lathe center. Drive apertures are formed radially outwardly of this center bore to receive drive pins from the machine tool. Most preferably the drive apertures are slots which provide clearance, facilitating the alignment of the drive pins in the drive apertures.
