Abstract

A method for manufacturing integrally bladed rotors (preferably gas turbine rotors) is provided. The method includes the steps of a) providing a basic rotor body; b) placing the basic rotor body into an electrolyte; c) electrochemically machining the basic rotor body by simultaneously manufacturing a plurality of unmachined blades; and d) subsequently machining the unmachined blades to provide hydrodynamic surfaces, in particular a suction side and a pressure side, in the area of each unmachined blade.
