Abstract

Procédé de fabrication d'une aube de rotor pour une turbomachine d'aéronef, cette aube comprenant un pied (12), une plateforme (14) et une pale (16), ledit pied comportant un bulbe inférieur (18), un col (20) intermédiaire, et une échasse supérieure (22), caractérisé en ce que, l'échasse ayant une forme générale de bloc et présentant deux faces latérales (24a, 24b) sensiblement parallèles entre elles et à un axe d'allongement dudit pied, cette échasse est usinée en réalisant un premier perçage (26) dans une direction (F1) parallèle auxdites faces et au niveau d'une première (24a) de ces faces, de façon à ce que ce premier perçage débouche latéralement sur cette première face, et un autre perçage (30) dans une direction (F3) perpendiculaire auxdites faces (24a, 24b), cet autre perçage étant relié audit premier perçage et débouchant sur ladite première face latérale.
