Abstract
When causing manual movement of a moving section of a machine tool, shape data of the moving section is made to move in a movement direction that has been input manually, and it is confirmed whether there is no interference with shape data of a surrounding interfering object. If interference occurs, a position returned a specified distance from the position where interference occurs is made a stop position, the moving section is moved to this stop position, and stopped at that position.
Claims2
A numerical control device for causing movement of a moving section of a machine tool, comprising:
- an operation input device for performing movement operations for the moving section manually;
- a memory for storing shape data of the moving section and shape data of an interfering object, that is capable of interfering with the moving section;
- an interference check section for confirming whether or not shape data for the moving section will interfere with shape data for the interfering object by moving in a movement direction input using the operation input device, and if there will be interference, calculating a stop position separated only a predetermined distance from an interference position in a direction opposite to the movement direction;
- and
- a function generator section for generating a function, for controlling axial movement of the moving section, based on a movement operation input from the operation input device, and, in the event that it has been determined by the interference check section that there is interference, generating a function to stop the movement section at the stop position.
