Title (EN) SYSTEM AND METHOD FOR MACHINING WORKPIECE OF LATTICE STRUCTURE AND ARTICLE MACHINED THEREFROM
(FR) SYSTÈME ET PROCÉDÉ D'USINAGE D'UNE PIÈCE DE STRUCTURE EN TREILLIS ET ARTICLE AINSI USINÉ
Abstract:
(EN) A system is configured for machining a workpiece (102, 104, 110) of a lattice structure, the system includes an electrode (902, 904, 905) of a lattice structure, an electrolyte supply, and a power supply. The workpiece and the electrode are intertwined with each other and electrically isolated from each other. The electrolyte supply is configured for circulating an electrolyte around and between the workpiece and the electrode. The power supply is configured for applying a voltage between the workpiece and the electrode to facilitate smoothing surfaces of the workpiece.
(FR) L'invention concerne un système conçu pour usiner une pièce (102, 104, 110) d'une structure en treillis, le système comprenant une électrode (902, 904, 905) d'une structure en treillis, une alimentation en électrolyte et une alimentation en énergie. La pièce et l'électrode sont entrelacées l'une avec l'autre et électriquement isolées l'une de l'autre. L'alimentation en électrolyte est conçue pour faire circuler un électrolyte autour de la pièce et de l'électrode et entre ces dernières. L'alimentation en énergie est conçue pour appliquer une tension entre la pièce et l'électrode en vue de faciliter le lissage des surfaces de la pièce.
