Abstract

Le présent document concerne un procédé d’usinage d’une paroi (302) en matériau composite à matrice céramique comprenant une première face (305) et une seconde face (303) opposées, le procédé comprenant au moins les étapes : déposer une couche sacrificielle (304) sur au moins une partie de la première face (305), usiner ladite paroi (302) avec un outil d’usinage (312) au travers la seconde face (305) de sorte que l’outil d’usinage (312) traverse la couche sacrificielle (304), retirer la couche sacrificielle (304), et dans lequel la couche sacrificielle (304) est agencée pour empêcher une désagrégation de la paroi (302) au cours de l’usinage de ladite paroi (302). Figure à publier avec l’abrégé : [Fig. 3]The present document relates to a method of machining a wall (302) of ceramic matrix composite material comprising a first face (305) and a second face (303) opposite, the method comprising at least the steps: depositing a sacrificial layer (304) on at least part of the first face (305), machine said wall (302) with a machining tool (312) through the second face (305) so that the machining tool (312) ) passes through the sacrificial layer (304), remove the sacrificial layer (304), and in which the sacrificial layer (304) is arranged to prevent disintegration of the wall (302) during machining of said wall (302) . Figure to be published with the abstract: [Fig. 3]
