Abstract
For shaping the leading edge () of blisk blades (), 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 () has a material allowance () 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.
