Abstract
The purpose of the present invention is to provide a device for controlling a machine tool with which it is possible to smoothly stop oscillation at an arbitrary timing without loss of cutting-chip-shredding performance, and to minimize shock produced in the machine tool. The present invention provides a devicefor controlling a machine tool for performing machining while causing a tool and a workpiece to oscillate relative to each other, the devicefor controlling a machine tool comprising: an oscillation command generation unitfor generating an oscillation command on the basis of a machining condition and an oscillation condition; an oscillation stoppage assessment unitfor assessing the timing of oscillation stoppage; and a position speed control unitfor causing, on the basis of a superimposition command generated by superimposing the oscillation command onto a position command or a position deviation, the tool and the workpiece to oscillate relative to each other. The oscillation command generation unitcauses the oscillation amplitude to gradually attenuate from the timing at which oscillation stoppage is communicated from the oscillation stoppage assessment unit
