Abstract
A numerical control device for a machine tool includes: a timing calculation unit configured to calculate a start timing of a post-reverse movement command by which a position, where the sum of velocities generated in response to a pre-reverse movement command and the post-reverse movement command becomes zero, is equal to a position distanced by an in-position width from the end point of the pre-reverse movement command; and a movement command start unit configured to start the post-reverse movement command in accordance with the start timing calculated by the timing calculation unit.
