Abstract

Système de commande d'un dispositif à commande numérique (7a, 7b), assurant la commande d'une machine-outil complexe (1a, 1b) en fonction d'un programme d'usinage. Ce système effectue la commutation entre des sélections de diamètre et de rayon d'une valeur de coordonnée avec un code G (9a, 9b) dans le programme d'usinage (8a, 8b). Etant donné que le code G peut commuter les sélections de diamètre et de rayon, on peut utiliser dans le programme une valeur spécifique se rapportant à un besoin d'usinage spécifique de la machine-outil. En outre, lorsqu'on combine des programmes d'usinage préparés séparément pour la sélection du diamètre ou du semi-diamètre, cette opération s'effectue aisément si l'on spécifie un code G, soit pour la sélection du diamètre soit pour la sélection du rayon, au début d'un programme.
