A, mechanical parts machining arrangement should be based on the structure of the parts and blank situation, as well as the positioning clamping needs to think about, the focus is on the rigidity of the workpiece is not destroyed.
1. The processing of the previous process can not affect the positioning and clamping of the next process, the intersection of general mechanical parts processing process should also be considered.
2. First stop the internal shape of the cavity plus process, and then stop the shape of the processing process.
3. The same positioning, clamping or the same knife processing process is best articulated to stop, in order to reduce the number of repeated positioning, the number of tool changes and the number of times to move the platen.
4. mechanical parts processing in the same device to stop multiple processes, should be arranged first on the workpiece rigid destruction of small processes.
Second, the tool concentration division method:
Is divided into processes according to the tool used, with the same tool to finish processing all parts on the part can be completed. In the second knife, the third to complete the other parts they can complete. This can reduce the number of tool changes, tighten the empty range time, reduce the unnecessary positioning error.
Third, to process parts in order method:
On the processing content of many parts, according to its structural characteristics of the processing part into several parts, such as internal shape, shape, surface or plane. General first processing plane, positioning surface, after processing holes; first processing simple geometric shape, and then processing complex geometric shape; first processing lower precision parts, and then processing higher precision requirements of the parts.
