Based on the principle of electrochemical machining, a new method for electrochemical machining of non-cylindrical pin hole using multi-segment cathodes is proposed. According to the theory, the parameters needed required on each electrode were calculated. By changing the voltage or current applied to each electrode, the processing shape can be controlled. The simulation experiment was carried out with COMSOL multi-physics coupling software, and the optimal electrolytic gap was obtained. In view of the fact that a straight line appears at both ends of the target machining curve, an electrode is added at both side to achieve the shape requirements. After parameter adjustment, the results of simulation are highly consistent with the target curve, which proves the practicability of the method and provides theoretical support and new ideas for the processing of non-cylindrical pin hole.
