METHOD FOR PRODUCING A ROTOR VANE FOR A TURBOMACHINE

摘要

The invention relates to a method for producing a rotor vane (10) for a turbomachine, comprising a step consisting in producing a rough casting, the heel of which has a downstream lip (121) with a transverse increased thickness (130) such that the lip has an upstream surface (134) substantially parallel to the above-mentioned axis, said method comprising an additional step of machining said increased thickness so that the downstream lip has an upstream surface (138) inclined in relation to the above-mentioned axis.

1. Method for producing a rotor blade for a turbine engine, said blade comprising a vane which is connected at one end to a root and at the opposite end thereof to a heel bearing upstream and downstream knife-edge seals, which are inclined at least in part relative to the longitudinal axis (X) of the blade, the method comprising a step which consists in producing a blank casting which is to be machined, wherein the downstream knife-edge seal is formed by casting having a transverse machining allowance in such a way that said knife-edge seal has an upstream face which is substantially parallel to the above-mentioned axis, and in that the method comprises an additional step which consists in machining said machining allowance so that the downstream knife-edge seal has an upstream face which is inclined relative to the above-mentioned axis.
