Abstract

Procédé (P) de fabrication d’une pièce de turbomachine, la pièce comportant un disque et une pluralité d’aubes,le procédé étant caractérisé en ce qu’il comprend :une étape (E1) de taillage par fraise-mère et/ou par pelage d’une pièce brute avec un premier outil de sorte à obtenir une pièce intermédiaire, une étape de finition (E2) au cours de laquelle la pièce intermédiaire est usinée de sorte à obtenir la pièce de turbomachine, selon un usinage différent d’un taillage par fraise-mère et/ou par pelage, l’usinage utilisant un deuxième outil différent du premier outil. Figure pour l’abrégé : Fig. 2
