Parameters and process of electrochemical machining of blades

Abstract

Electrochemical processing is processing techniques combined electric spark machining with digital control machine technology. Electrolytic process generating method is used to cast the impeller blades and hub surface. It is effective method to improve the accuracy of the impeller to reduce flow resistance. The shape of the cathode tool is taper shank ball. According to the experimental data is used to determine the processing parameters. The five-axis CNC EDM machine is used to complete the turbine blades and hub of the surface processing. Machined surface roughness gets to the design requirements.
