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.
Claims4
A numerical control device for a machine tool, configured to, when carrying out processing of an object by controlling axes of a machine tool in accordance with a processing program including a command by which the direction of movement of one or more axes is reversed, start a post-reverse movement command in such a manner that a reversal position of the one or more axes comes within an in-position width of an end position of a pre-reverse movement command,
- the numerical control device for a machine tool comprising:
- a timing calculation unit configured to calculate a start timing of the post-reverse movement command by which a position, where a sum of the velocities generated in response to the pre-reverse movement command and the post-reverse movement command becomes zero, is equal to a position distanced by the in-position width from the end position 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.
