A machine tool control device (180) comprising a control unit (181) that controls a feed action and a relative rotation of a tool and a material, wherein the control unit combines an outbound feed movement and a return movement, said outbound feed movement being in a work direction of the material by the tool and said return movement being in a reverse work direction, and thus performs control such that cutting work is performed while the tool is made to move in relation to the material. Also provided are: a return position calculation unit (191) that, on the basis of a number of vibrations and a feed quantity that are predetermined for one rotation of either the tool or the material, calculates a return position of the tool when one vibration is complete; an outbound feed setting unit (192) that sets the outbound feed movement on the basis of a change point setting value determining a change point from the work direction to the reverse work direction, and causes the tool to arrive at the determined change point; and a return movement setting unit (193) that sets a pulse signal, said pulse signal being outputted as a return movement command, such that the tool arrives at the calculated return position when one vibration is complete.
