Abstract

L'invention concerne un appareil d'usinage à commande numérique capable d'empêcher facilement la production d'ébardures continues. Un outil (2) commence les nouvements d'usinage en un point P1 et effectue l'usinage le long d'un axe Z. Il s'arrête ensuite temporairement en un point P3 situé à une distance L2 du point P1, et revient en un point P4 en parcourant une distance L3, point depuis lequel l'outil continue l'usinage. L'outil s'arrête et revient en arrière de manière répétée à chaque fois qu'il a parcouru la distance L2, et effectue l'usinage en un point P2. Cette opération d'usinage s'effectue à l'aide d'un programme simple.
