This paper expounds the cavity, the hole, the narrow slot and the text of the mold part, and the method of electric discharge machining is adopted in the position where the CNC machine tool is difficult to process or it is difficult to achieve satisfactory machining accuracy due to structural factors. Using the software as a tool, the CimatronE electrode design method for extracting the discharge surface, establishing the electrode reference table, establishing the relationship between the discharge surface and the reference table, loading the standard electrode holder and generating the engineering drawing is described in detail, and discussing the electrode design theory in the design. The CimatronE electrode design method has high practicability in practical work, and the operation is simple and easy to learn. It is widely used safely and efficiently, and is suitable for workpieces of various complicated parts.
