Gear milling and Gear hobbing

Gear hobbing is a machining process in which gear teeth are progressively generated by a series of cuts with a helical cutting tool hob All motions in hobbing are rotary and the hob and gear blank rotate continuously as in two gears meshing until all teeth are cut when bobbing a spur gear the angle between the hob and gear blank axes is 90° minus the lead angle at the hob threads.
