摘要： 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: setting means (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 a value of at least one of the parameters; and correcting means (C1) for setting each of the rest of the parameters to a predetermined value and correcting the value of the at least one of the parameters set by the setting means on the basis of the value of the each of the rest of parameters, so that the value of the at least one of the parameters set by the setting means (C1, C2) can be corrected by the correcting means (C1) for machining the workpiece.
