1. First, select the appropriate processing method for each surface according to the processing accuracy requirements and the roughness of the processed surface.

2. The positioning benchmark of each process should be reasonably selected according to the thickness benchmark requirements.

3. On the basis of the analysis of the parts, distinguish the thickness of the processing, and determine the concentration of each process, and then arrange the processing sequence of each surface reasonably, so as to formulate the machining process route of the parts.

4. Determine the machining allowance of each process and the size and tolerance of each process.

5. Under the premise of ensuring quality and considering economy, select suitable machine tools and tools, clamps, measuring tools and cutting tools.

6. Determine the technical requirements and inspection methods of each major Tunghsu.

7. In order to ensure the rationality of production and the balance of rhythm, it is necessary to select the appropriate cutting amount and time quota, and do not change it at will.

8. The operator fills in the process documents as required.
