There are several methods for cutting gear teeth. Two common methods are: 1. Shaping Mill: In this method, a shaping mill is used to cut the gear teeth to fit the tooth space. A different cutter is needed for each gear because the tooth space shape varies depending on the number of teeth. However, it has been determined that only eight cutters are needed to cut any gear in the range of 12 teeth up to the rack with reasonable accuracy. A separate set of cutters is required for each pitch. 2. Pinion or Rack Cutter: In this method, teeth can be generated by a pinion or rack cutter. The pinion cutter moves alternately along the vertical axis and slowly advances, penetrating the body of the gear to the required depth. When the pitch circles are tangent, both the cutter and the gear disk rotate a little after each cutting stroke. As each tooth of the cutter is a cutting tool, all teeth will be cut after the gear disk has completed one rotation. The sides of a rack involute tooth are cut by a cutter that is shaped like a rack and is fed into the gear blank. These are just a couple of methods used for cutting gear teeth. There are other methods as well, depending on the specific requirements and manufacturing processes.
