Abstract

L'invention concerne un dispositif permettant d'usiner toutes les faces d'une pièce en une opération de montage par serrage. Seules les zones requises pour fixer la pièce demeurent toujours inaccessibles à l'outil. Selon la revendication 1, l'invention concerne au moins deux dispositifs à cinématique parallèle (2, 3) comportant chacun une plate-forme de travail pour fixer le système d'outil (8) respectif, la pièce (11) ou l'établi. L'invention diffère des dispositifs d'usinage traditionnels, en ce que l'utilisation de plusieurs dispositifs à cinématique parallèle (2, 3), comme plans support et l'utilisation d'au moins un plan rotatif (4) permettent de déplacer non seulement le système d'outil (8), la pièce (11) ou l'établi, dans tous les degrés de liberté, par la commande (5), mais également le système de coordonnées tridimensionnelles (X, Y, Z), auquel se rapporte l'outil (10) lors de l'usinage de la pièce (11), par rapport au système de coordonnées de référence (Xr, Yr, Zr), qui se rapporte au socle de la machine.
