Definitions

  • the numerical control device 1 reverses the actual direction of movement of the feed axis based on the information indicating the movement amount per unit time included in each of the plurality of files 23 stored in the first storage unit 3. It further has a calculation unit 4 that detects and calculates the actual amount of movement of the feed shaft after the direction of movement of the actual feed shaft is reversed. Since the movement amount per unit time includes information indicating the direction in which the actual feed axis moves, the calculation unit 4 moves the actual feed axis based on the information indicating the direction in which the actual feed axis moves. Inversion of the direction of can be detected. The calculation unit 4 calculates the actual movement amount of the feed axis after the direction of movement of the actual feed axis is reversed, based on the information indicating the movement amount per unit time included in each of the plurality of files 23 can do.

Abstract

L'invention concerne un dispositif de commande numérique (1) comprenant : une unité de calcul (4) destinée à calculer, en fonction de la quantité de mouvement par unité de temps d'un arbre d'avance réelle comprenant des informations indiquant le sens dans lequel se déplace l'arbre d'avance réelle d'une machine-outil (10), la quantité de mouvement dudit arbre après inversion du sens de déplacement de l'arbre ; une unité de détermination (5) destinée à déterminer s'il faut exécuter une correction de mouvement perdu en fonction de la quantité de mouvement calculée par l'unité de calcul (4) ; et une unité de commande (8) qui n'exécute pas la correction de mouvement perdu lorsqu'il a été déterminé par l'unité de détermination (5) qu'une correction de mouvement perdu ne doit pas être exécutée.
