The formulation of mold manufacturing process regulations is a systematic process, which mainly includes the following steps: First, it is necessary to study and digest assembly drawings and parts drawings, and carry out processability analysis. Next, the type of production is determined, which will influence the subsequent process selection and process scheduling. Then, select the positioning datum and the processing method of the main surface, and formulate the processing process route of the mold parts. After determining the processing route, it is necessary to list in detail the specific content, size, allowance and technical requirements of each process. In addition, mold manufacturing is a professional course, which covers the basic theory of machining technology, the machining of mold parts and special processing methods.
