  • ECM(electrochemical machining) is one of the main machining methods of the aero-engine blades production. However, the tool cathode design is very difficult, which limits the applications of ECM in modern industries. To solve the difficulties in automation of the tool cathode design of aero-engine blades in ECM, a specialized expert system of computer aided cathode design for aero-engine blades in ECM was developed on the basis of electrochemical machining foundational theories. The basic structure, module components and work principle of this expert system were discussed in detail. The finite element cathode design arithmetic based on the mathematics model of actual electric field distribution in electrode gap in ECM process was proposed. The experiments for verifying the machining accuracy of the design cathode were developed. The experimental results demonstrate that this cathode design expert system has high design accuracy and excellent operating stability.
