To provide a controller for a machine tool which can shred scraps and perform accurate cutting without performing a so-called finishing process.SOLUTION: Provided is a controller for a machine tool comprising: a rocking operation command generation unit for generating, on the basis of a condition under which a rocking operation is performed, a rocking operation command for causing a workpiece and a tool to be oscillated relatively to each other in the radial direction of the workpiece; a movement command generation unit for generating a movement command for causing the workpiece and the tool to be moved relatively to each other in order to cut screw-threads in the workpiece; an adder for adding the rocking operation command and the movement command together; and a determination unit for previously determining whether or not to add the rocking operation command to the movement command. The adder outputs, on the basis of the determination result of the determination unit, a superimposed command composed by including one or a plurality of machining patterns in which a total movement command with the rocking operation command added and a total movement command with the rocking operation command not added, are combined arbitrary numbers of times, respectively.SELECTED DRAWING: Figure 1
