IPC: B24B9/14
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce the machining time, and to improve the machining efficiency by checking the completion of machining for each radius vector angle based on the machining data, and performing the machining while changing the rotational speed judging whether or not the completion of machining is checked.
