The arrangement of the processing sequence should be considered according to the structure of the part and the condition of the blank, as well as the needs of positioning and clamping. The important point is that the rigidity of the workpiece is not destroyed. The order should generally be carried out according to the following principles:
The CNC processing of the previous process cannot affect the positioning and clamping of the next process, and the general machine tool processing processes should also be considered comprehensively. Carry out the inner cavity adding process first, and then the outer shape processing process. The processes of CNC machining with the same positioning, clamping method or the same tool are best connected to reduce the number of repeated positioning, tool change times and the number of times of moving the platen. For the multiple processes carried out in the same installation, the process should first be arranged with less damage to the rigidity of the workpiece.
