Abstract
The vertical movement cycle and trajectory inclination angle of a cutter are switched so that when a main spindle is moving downward, a head is moved to position the cutter at a machining location, and the cutter is lowered rectilinearly; that when the main spindle is moving upward, the head is moved to position the cutter at a withdrawal location; that, when an external gear is to be generated by cutting, relieving means for rectilinearly raising the cutter cause the machining location to be positioned on one radial side of the cutter and move the cutter downward parallel to the axis of a workpiece; and that when an internal gear is to be generated by cutting, said relieving means cause the machining location to be positioned on the other radial side of the cutter and move the cutter downward parallel to the axis of the workpiece.
