Abstract:
For shaping the leading edge (1) of blisk blades (2), the shape, amount and disposition of the material to be removed in a subsequent grinding and polishing process is determined beforehand over the entire blade length. The blade leading edge is milled such that an elliptical profile (3) has a material allowance (7) which over the length of the leading edge exactly corresponds to an expected material removal during the grinding and polishing process, so that a blisk blade is produced whose leading edge features an aerodynamically advantageous shape.
