The purpose of the present invention is to provide a control device for a machine tool that can reliably chop chips while suppressing vibration of the machine tool. A control device (1) for a machine tool machines by relatively oscillating a tool and a workpiece, the control device comprising: an oscillation command generation unit (13) that calculates an oscillation amplitude and an oscillation frequency from a machining condition and generates an oscillation command; and a position-speed control unit (17) that relatively oscillates the tool and the workpiece on the basis of a superimposed command generated by superimposing the oscillation command generated by the oscillation command generation unit (13) on a position command or a position deviation. The oscillation command generation unit (13) changes the oscillation amplitude and/or the oscillation frequency during machining.
