See full text

A control apparatus of a machine tool includes: a slide position control unit configured to control a slide according to operation patterns; a pressure command generation unit configured to generate a pressure command for a die cushion according to the operation patterns; a pressure detection unit configured to detect an actual pressure of the die cushion; a die cushion speed control unit configured to control the die cushion, based on an error between the pressure command and the actual pressure; and a command reach determination unit configured to determine whether or not the error is greater than a pressure threshold, wherein the slide position control unit sets, based on a result of the determination by the command reach determination unit, a waiting period between the operation pattern at the time of the determination and the next operation pattern, wherein the slide is kept at its position during the waiting period.
