    ProcessesReferencesFurther ReadingBroachingFor very large gears or spline, a vertical broach is used. It consists of a vertical rail that carries a single tooth cutter formed to create the tooth shape. A rotary tableand a Y axis are the customary axes available. Some machines will cut to a depth on the Y axis and index the rotary table automatically. ThHobbingHobbing is a method by which a hobis used to cut teeth into a blank. We gear hobbing with a master hob or index hob on gear hobbing machines who cut, gears, wheels, pinions, shafts and worms. The cutter and gear blank are rotated at the same time to transfer the profile of the hob onto the gear blank. Milling or grindingSpur may be cut or ground on a milling machine or jig grinder utilizing a numbered gear cutter, and any indexing heador rotary table. The number of the gear cutter is determined by the tooth count of the gear to be cut. To machine a helical gear on a manual machine, a true indexing fixture must be used.
