PROBLEM TO BE SOLVED: To provide a control device for gear machining capable of performing gear machining with high machining accuracy. SOLUTION: This control device for gear machining drives a workpiece 2 and a tool 1 for gear machining by motors 15 and 27 and performs gear cutting and tooth flank finishing for the workpiece 2. Motor control means 11, 12, 13 or 21, 22, 23 for controlling position and speed of each of the motors 15 and 25 are provided with position correction means 41 and 42. The position correction means 41 and 42 correct correction amount based on position deviation one cycle before of repeated prescribed cycles into a position command and the corrected position command is formed into a position command of a position loop processing. Since a synchronization error becomes small, the gear machining with high accuracy can be performed. COPYRIGHT: (C)2003,JPO
