In this thesis the manufacture of fir tree slots in nickel-based alloys by wire EDM was fundamentally investigated. The motivation arises from the jet engine manufacturers' need for an economical manufacturing process to substitute broaching. It was demonstrated, that the wire EDM process is capable to substitute the broaching process for fir tree slot production in terms of technological and economic performance.
