Abstract
Provided is a control device for a machine tool that can suitably shred chips in a state without good conformability. A control device for a machine tool which oscillates a tool and a workpiece relative to each other while machining comprises: a comparison unit that compares the oscillation amplitude calculated value calculated by an oscillation amplitude calculation unit and the oscillation amplitude minimum value set by a minimum value setting unit; an oscillation command generation unit that generates an oscillation command on the basis of the oscillation condition and the value of the oscillation amplitude obtained from the comparison results of the comparison unit; and a position/speed control unit that oscillates the workpiece and the tool relative to each other on the basis of a superimposition command obtained by superimposing the oscillation command over a position command.
