Abstract
A control unit that relatively moves a headstock and tailstock and a tool to thereby machine a peripheral surface of a workpiece in a radial direction executes control such that a relative feed speed of the tool in the radial direction in a transitional state where an amount of warpage of the workpiece in the radial direction at a machining position increases is faster than a relative feed speed of the tool in the radial direction in a steady state where an amount of warpage of the workpiece in the radial direction at the machining position is constant. By so doing, it is possible to reduce a machining time at the time of the start of machining.
