ABSTRACT
The gear shaper cutter is the primary type of gear cutting tool for machining of internal spur and helical gears. Before designing a shaper cutter for machining of a given internal gear, the generating surface of the gear cutting tool should be determined. To determine the generating surface of the shaper cutter, the internal gear machining mesh is used. The internal gear machining mesh is one of the many possible types of gear machining meshes classified in Figure 3.8.
