In the machining process, the operator must perform the mechanical fore processing according to the operating rules. Then how to perform the correct operation in the machining process of the part?
1, first of all according to the processing accuracy requirements and the surface roughness of the surface of each surface to select the appropriate processing method.
2. It is necessary to reasonably select the positioning reference for each process according to the requirements of thickness and reference.
3. On the basis of the analysis of the parts, divide the fine and fine processing, and determine the concentration degree of each process, arrange the processing sequence of each surface reasonably, and then formulate the mechanical processing route of the parts.
4. Determine the machining allowance for each process and the dimensions and tolerances of
each process.
5. Under the premise of guaranteeing quality and considering economy, choose the right machine tool, work clamp, quantity and cutting tool.
6. Determine the technical requirements and test methods of each major Dongxu.
7. In order to ensure the rationality of production and the balance of the rhythm, it is necessary to select the appropriate cutting amount and time quota, which cannot be arbitrarily changed.
8.The operator fills in the process documents as required
