Abstract
A machine tool according to an aspect of the present disclosure comprises: a plurality of servo motors; a plurality of servo amplifiers that drive the servo motors, respectively; and a numerical value control device that inputs a command value to the plurality of servo amplifiers in accordance with a processing program. The numerical value control device has: a motor classification unit that classifies the plurality of servo motors into continuous drive motors which require continuous excitation during execution of the processing program and intermittent drive motors in which excitation can be stopped at least temporarily during the execution of processing program; and a stop control unit that stops the excitation of at least one of the intermittent drive motors during the execution of the processing program.
