Abstract
Provided is a control device for a machine tool that machines a workpiece by vibration-controlling a control shaft, wherein shaking of the machine tool as a whole is reliably suppressed. This control device for a machine tool includes: a vibration condition setting unit that sets a vibration condition including at least one of a frequency parameter comprising a vibration frequency or a vibration frequency multiple, an amplitude parameter comprising a vibration amplitude or a vibration amplitude multiple, and a vibration direction; a vibration upper limit setting unit that sets, in accordance with one or both of the vibration frequency and the vibration direction, an upper limit value of the vibration parameter that is determined by the vibration condition and includes at least one of the vibration frequency, the vibration amplitude, a vibration speed, a vibration acceleration, and a vibration jerk; a vibration condition limiting unit that limits, on the basis of the upper limit value of the vibration parameter, the vibration condition set by the vibration condition setting unit; and a vibration control unit that vibration-controls a control shaft on the basis of the vibration condition limited by the vibration condition limiting unit.
