Abstract: A numerical control device for a machine tool, the machine tool including: a reference shaft that moves a tool or a workpiece; and a superimposition shaft that moves a tool or the workpiece. The numerical control device superimposes the movement amount of the reference shaft on the movement amount of the superimposition shaft. The numerical control device including a control computation unit that, in response to a superimposition control command, changes at least one of a first vibration rate, a second vibration rate, and a main shaft rotation speed on a basis of a first vibration command, a second vibration command and a main shaft rotation speed command such that the first vibration rate stays constant and the second vibration rate stays constant. The first vibration rate is a number of times that of the reference shaft vibrates per rotation of a main shaft.
