Abstract

Une rectifieuse en coordonnées (1-3, 6, 10) comprend des capteurs (11, 14, 16) dont les signaux sont traités, partiellement visualisés ou transmis à une commande numérique par calculateur (21) par un appareil central (18) de commande et de visualisation. Des capteurs (14) disposés sur la pièce (7) ou sur son porte-pièce servent à saisir le contact avec l'outil, afin d'empêcher la 'rectification dans le vide' et d'assurer une visualisation optique et acoustique du contact avec l'outil. Un capteur (16) disposé sur le moteur de rectification (1) sert à contrôler l'équilibrage. Un capteur (11) est fixé sur une plaque de référence (10) par rapport à laquelle l'outil (2) peut être guidé afin de déterminer avec précision les dimensions de l'outil. La réunion desdites fonctions de commande et de contrôle dans un seul dispositif permet d'augmenter considérablement la productivité et la précision des opérations d'usinage.
