Abstract
Procédé (100) de fabrication d’une aube (30) de turbomachine, comprenant les étapes : réaliser une aube (30) comprenant une pale (32) s’étendant selon une première direction (d1), la pale (32) comprenant un bord d’attaque (34) et un bord de fuite (36) entre lesquelles s’étend au moins une première face (32a) de la pale (32) ; abraser une zone de bord de fuite (A) de la première face (32a) de la pale (32), au moyen d’une installation comportant un premier dispositif (50), le premier dispositif (50) comprenant une première bande abrasive (54) entrainée en rotation autour d’au moins deux cylindres (56a ; 56b) et un premier galet (52) présentant une face d’appui (52a) ayant un profil complémentaire d’au moins une partie de la zone de bord de fuite (A) de la première face (32a) de la pale (32) à obtenir. Figure de l’abrégé : Figure 5Method (100) for manufacturing a turbine engine blade (30), comprising the steps: producing a blade (30) comprising a blade (32) extending in a first direction (d1), the blade (32) comprising a leading edge (34) and a trailing edge (36) between which extends at least a first face (32a) of the blade (32); abrading a trailing edge zone (A) of the first face (32a) of the blade (32), by means of an installation comprising a first device (50), the first device (50) comprising a first abrasive belt ( 54) driven in rotation around at least two cylinders (56a; 56b) and a first roller (52) having a support surface (52a) having a profile complementary to at least part of the trailing edge zone (A) of the first face (32a) of the blade (32) to be obtained.
