Title (EN) METHOD FOR PRODUCING AN ECM TOOL AND USE THEREOF AS A CATHODE IN ELECTROCHEMICAL MACHINING OF A WORKPIECE
(FR) PROCÉDÉ DE PRODUCTION D'UN OUTIL D'USINAGE ÉLECTROCHIMIQUE ET UTILISATION DE CELUI-CI EN TANT QUE CATHODE DANS UN USINAGE ÉLECTROCHIMIQUE D'UNE PIÈCE À TRAVAILLER
Abstract:
(EN) According to a first aspect, the invention relates to a method for producing a tool (20) which is used as a cathode in the electrochemical machining (ECM) of a workpiece (70) made from metal or a metal alloy to produce a product, which method comprises electroforming a negative (20) of one or more surfaces of the product. A second aspect relates to the use of a tool produced by the method according to the invention as cathode in the electrochemical machining (ECM) of a workpiece (70).
(FR) Selon un premier aspect, l'invention porte sur un procédé pour produire un outil (20) qui est utilisé en tant que cathode dans l'usinage électrochimique (ECM) d'une pièce à travailler (70) réalisée en métal ou en un alliage métallique pour produire un produit, lequel procédé comprend l'électroformage d'un négatif (20) d'une ou plusieurs surfaces du produit. Un second aspect porte sur l'utilisation d'un outil produit par le procédé selon l'invention en tant que cathode dans l'usinage électrochimique (ECM) d'une pièce à travailler (70).
