Abstract
This invention provides a machine tool that, in addition to sequentially separating a chip generated from a workpiece in a reliable manner, improves the roundness of the finished workpiece and improves the visual appearance and roughness of a machined surface of the workpiece, and a control apparatus of the machine tool. A machine tool or a control apparatus thereof includes a vibration frequency setting unit for setting vibration frequency of the reciprocal vibration with respect to one relative rotation when machining a workpiece so that the intersections of paths of a cutting tool during forward movement and backward movement are dispersed on a circumferential surface of the workpiece.
