Abstract

Electrode permettant l'usinage de trous ayant des surfaces de diffusion. Elle comprend au moins une dent 42 possédant une extrémité orientée longitudinalement 43 et une base 44 qui relie cette extrémité au corps 38, cette base possédant une surface biseautée qui fait avec l'axe de l'extrémité orientée longitudinalement un angle tel que lorsqu'on approche cette dent de la pièce et qu'on l'y fait pénétrer, cette surface biseautée produit une érosion qui se traduit par un trou de diffusion. Application aux aubes de turbomachine.
