Taking the process completed by the same tool as a working procedure, this division method is suitable for situations where there are many workpiece surfaces to be machined. Machining centers often use this method to complete.
Take the technological process that can be completed in one clamping of the parts as a process. This method is suitable for parts with few processing contents. Under the premise of ensuring the processing quality of the parts, all processing contents are completed in one clamping.
The part of the process completed in rough machining is regarded as one process, and the part of process completed in finishing is regarded as another process. This division method is suitable for parts that have strength and hardness requirements, require heat treatment or require high accuracy of parts, need to effectively remove internal stress, and have large deformations after machining, which need to be divided according to rough and finishing stages.
The part of the process that completes the same profile is regarded as a process. For parts with many machining surfaces and more complicated, the sequence of CNC machining, heat treatment and auxiliary processes should be arranged reasonably, and the connection problem between the processes should be solved.
