Abstract

L'invention concerne une machine-outil à commande numérique. Selon unité de commande numérique comporte une mémoire dans laquelle sont mémorisées des valeurs de coordonnées correspondant au tranchant de chacun des outils. Lorsqu'un changement d'outil se produit, les valeurs de coordonnées mémorisées dans des registres de position actuelle sont corrigées de la différence entre les coordonnées de position actuelle et les coordonnées mémorisées. L'invention s'applique notamment aux machines-outils commandées par calculateur.The invention relates to a numerically controlled machine tool. According to the digital control unit has a memory in which are stored coordinate values corresponding to the cutting edge of each of the tools. When a tool change occurs, coordinate values stored in current position registers are corrected for the difference between the current position coordinates and the stored coordinates. The invention applies in particular to machine tools controlled by a computer.
