CA 2735551

The invention relates to a method for activating a workpiece manipulator (4) of a machine tool (1), comprising a control device which prescribes machining paths (6) for a workpiece by means of a computing unit, which machining paths are travelled by the workpiece manipulator (4) from a machine starting position (A), wherein the workpiece (5) which can be moved by the workpiece manipulator (4) in a multi-axially translatory and preferably also rotating manner is passed to a plurality of tools (3) one after the other for the step-by-step machining. In order to provide advantageous conditions it is proposed that in the case of termination of machining the workpiece manipulator (4) is made to move with the workpiece (5) back over the path of movement (7) assigned to the respective machining step into a position (8) prior to this machining step, in which the workpiece manipulator is optionally stopped or from which the workpiece manipulator is moved into the machine starting position (A).

Procédé de commande d'un manipulateur de pièce (4) d'une machine-outil (1) comportant un dispositif de commande qui prédéfinit à l'aide d'une unité de calcul avec le manipulateur de pièce (4) à partir d'une position de départ (5) de la machine des trajectoires d'usinage (6) à parcourir pour une pièce, la pièce (5) pouvant être déplacée à l'aide du manipulateur de pièce (4) en translation selon plusieurs axes et de préférence aussi en rotation et étant acheminée, pour un usinage par étapes, tour à tour à une pluralité d'outils (3). L'objet de la présente invention est de créer des conditions avantageuses. A cet effet, en cas d'interruption du processus d'usinage, le manipulateur de pièce (4) avec la pièce (5) sont renvoyés sur la trajectoire de déplacement (7) associée à l'étape d'usinage concernée jusqu'à la position de départ (8) précédant ladite étape, après quoi le manipulateur de pièce est sélectivement stoppé ou ramené à la position de départ (5) de la machine.
