The process division methods of machining parts on CNC machine tools are:
1) The tool centralized sorting method is to divide the processes according to the tools used, and use the same tool to process all the parts that can be completed on the part. Use the second and third knives to complete other parts they can complete. This can reduce the number of tool changes, reduce idle time, and reduce unnecessary positioning errors
2) Roughing and finishing process method For a single part, rough machining, semi-finishing, and then finishing are required. Or a batch of parts, firstly all roughing and semi-finishing, and finally finishing, between roughing and finishing, it is better to wait for a period of time, so that the deformation of the parts after roughing can be fully recovered, and then finishing. Improve the machining accuracy of parts
3) According to the order of processing parts, generally the plane, positioning surface, and hole are processed in advance. The simple assembly shape of the foresight is used to process complex geometric shapes; the parts with lower precision are processed first, and the parts with higher precision requirements are processed first. .
In a word, in cnc machine tool processing parts, the division of the processing procedures should be analyzed in detail according to the specific conditions of the processed parts, and the arrangement of many procedures is comprehensively arranged according to the appeal division method.
