Abstract
To provide a machine tool and a control device for the machine tool that can smoothly cut a workpiece while segmenting chips by feeding a cutting tool in a feed direction while reciprocally vibrating the cutting tool along the feed direction on the basis of a condition set by a user. The machine tool (100) or the control device (C) includes: a setting unit (C1, C2) for utilizing a number of rotations of relative rotation of a workpiece (W) and the cutting tool, a number of reciprocal vibrations of the cutting tool per rotation of the relative rotation, and a vibration frequency dependent on a period in which the control device (C) can execute an operating instruction when the workpiece W is machined as parameters and for setting values of two of the parameters to a control section (C1); and a correcting unit (C1) for setting the remaining one of the parameters to a predetermined value and correcting the values of the two of the parameters set by the setting unit on the basis of the value of the remaining one of the parameters.
