Title
(EN) APPARATUS FOR THE LIGHTENING OF PANELS OR THIN PLATES BY REMOVAL OF THE MATERIAL
(FR) APPAREIL DESTINÉ À ALLÉGER DES PANNEAUX OU DES PLAQUES MINCES PAR ENLÈVEMENT DE MATIÈRE
Abstract
(EN)
The invention concerns an apparatus for lightening of thin, flexible and shaped workpieces, such as panels or sheet metals, by removal machining of material from surfaces thereof, on a machining unit having a worktable and a counterthrust means designed to rest against a part of the surface of the workpiece opposed to the one on which said tool must work from time to time. The worktable (13) comprises supporting means (23) of the workpiece to be machined, and gripping means (28) designed to support the workpiece during its machining independently from said supporting means. The counterthrust means consist of a board (14) movable according to several axes and carrying a plurality of supporting elements (33). The supporting elements (33) can be individually translated or in groups between a draw-in position and an extended position to define a supporting plane depending on the shape of the surface of the workpiece against which the counterthrust means must rest. The invention further concerns a method for mapping the workpiece surface by means of the supporting elements.
(FR)
L'invention concerne un appareil destiné à alléger des pièces minces, souples et profilées, telles que des panneaux ou des tôles métalliques, par usinage avec enlèvement de matière de leurs surfaces, sur une unité d'usinage dotée d'une table et d'un moyen de contre-poussée conçu pour s'appuyer contre une partie de la surface de la pièce opposée à celle sur laquelle ledit outil doit travailler par intermittence. La table (13) comporte un moyen (23) d'appui de la pièce à usiner, ainsi qu'un moyen (28) de bridage conçu pour soutenir la pièce pendant son usinage indépendamment dudit moyen d'appui. Le moyen de contre-poussée est constitué d'une planche (14) mobile suivant plusieurs axes et portant une pluralité d'éléments (33) d'appui. Les éléments (33) d'appui peuvent être translatés individuellement ou par groupes entre une position escamotée et une position déployée pour définir un plan d'appui dépendant de la forme de la surface de la pièce contre laquelle le moyen de contre-poussée doit s'appuyer. L'invention concerne en outre un procédé de mise en correspondance de la surface de la pièce au moyen des éléments d'appui.
