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...
The procedure for cathode design in electrochemical machining (ECM) is plagued by limited applicability, inaccuracy, and nonconvergence. So cathode design is a difficult problem must be faced and solved in ECM. We develop a new numerical approach for cathode design by employing a finite element method and this approach has been applied in the cathode design of aero-engine blades in ECM. The mathematic...
Electrochemical machining (ECM) is one of the most vital produce methods of aero-engine blades due to the high efficiency and surface quality, stress free and no tool loss. However, the main difficulties encountered with ECM are tool cathode design problem. To solve the problem, an accurate model and numerical approach based on the potential distribution in inter-electrode gap is proposed in this...
