Abstract
A control device for a machine tool for cutting a rotationally-symmetric workpiece by a tool, includes a machining command making unit for making a machining command for an auxiliary motor based on rotation speeds of the workpiece and the tool, and feed rates of the tool and the workpiece, an oscillation command making unit for making an oscillation command for the auxiliary motor, based on the rotation speeds and the feed rates, so that the oscillation command is asynchronous with the rotation speed of the workpiece around the axis of rotation, and so that the tool intermittently cuts the workpiece, an addition unit for adding the oscillation command to the machining command, and a control unit for controlling the auxiliary motor based on the machining command to which the oscillation command has been added.
