Abstract

To provide a machine tool and a control device for the machine tool that allows a user to select the vibration condition according to an input number of rotations and an input number of vibrations. The control device (184) for the machine tool (180) includes: inputting means (182) for inputting a relative number of rotations or a relative number of vibrations of the cutting tool (130) and a workpiece (W), selecting means (183c) for making it possible to select a combination of each parameter consisting of a number of rotations and a number of vibrations that are obtained on the basis of a vibration frequency dependent on a period, in which an operating instruction can be executed to the vibration means (150) and (160), and the number of rotations or the number of vibrations that is input via the inputting means (182), and setting means for setting each parameter of the number of rotations and the number of vibrations in the control section on the basis of a predetermined combination selected from combinations that are got selectable by the selecting means (183)
