MACHINE TOOL CONTROL DEVICE, AND MACHINE TOOL EQUIPPED WITH SAID CONTROL DEVICE

摘要

The purpose of the present invention is to provide a machine tool and a control device for the machine tool such that it is possible to smoothly cut a workpiece by feeding a cutting tool in the machining feed direction while reciprocally vibrating the cutting tool on the basis of the conditions set by a user, and to improve the outward appearance of the work surface of the workpiece. In this machine tool (100) and this control device (C) for the machine tool (100), a control means (C1) is configured so as to set the rotational speed of relative rotation and the number of reciprocal vibrations per revolution of the relative rotation according to the repetitive movement frequency caused by an operation instruction cycle, and an adjusting means adjusts the rotational speed or the number of vibrations set by the control means.
