Abstract
A gear machining apparatus creates a gear on a workpiece W by moving a gear cutting tool relatively with respect to the workpiece along the direction of the rotation axis of the workpiece W while synchronously rotating the gear cutting tool and the workpiece. One of a workpiece rotation speed controlling portion and a tool rotation speed controlling portion varies the rotation speed of one of the workpiece and the gear cutting tool and the other one of the workpiece rotation speed controlling portion and the tool rotation speed controlling portion synchronizes the rotation speed of the other one of the workpiece and the gear cutting tool with one of the rotation speed of the workpiece and the gear cutting tool.
