This course will provide instruction in the theory and practical application of techniques for the development of pinion tooth surfaces for gears cut by the face hobbing (3 axis) cutting method. The class will also discuss the lapping of face hobbed gears. This class is offered using either typical high speed steel blades with coolant or dry power cutting with carbide blades.
