Abstract
Provided is a machine tool control device that makes it possible to alleviate shock generated in a machine tool during an oscillation cutting process. A control devicefor a machine tool that carries out a process by relatively oscillating a tool and a workpiece is provided with: an oscillation command generation unitthat generates an oscillation command on the basis of an oscillation condition; an oscillation start/end determination unitthat determines start/end of oscillation on the basis of the oscillation command; and a position speed control unitthat relatively oscillates the tool and the workpiece on the basis of a superimposed command generated by superimposing the oscillation command on a moving command according to a determination result of the oscillation start/end determination unit. The oscillation start/end determination unitdetermines start/end of oscillation when the absolute value of the oscillation command is no greater than a predetermined value.
