Fig: 1 Through a series of cuts performed with a cutting device known as a hob, the gear's teeth or splines are gradually carved into the material (a flat, cylindrical piece of metal) Working Of Gear Hobbing The process of Gear hobbing, the gear is cut by a generating process in which the gear blank and the cutter is rotated at the same time along with a fixed gearing ratio between hob and gear blank. Gear blank is fed into the revolving hob throughout this procedure until the necessary depth is obtained. Until all of the teeth are formed, the hob is fed through the blank's face. When hobbing a spur gear, the hob teeth are positioned parallel to the blank's axis of rotation. The axis of the
