The arrangement of the processing sequence should be considered according to the structure of the parts and the status of the roughness, as well as the needs of positioning and clamping. The focus is that the rigidity of the workpiece is not destroyed. The order should generally be carried out in the following principles:

The CNC processing of the upper process cannot affect the positioning and clamping of the lane process. Those who are interspersed with general machine tool processing processes must also be comprehensively considered. Advance the inner cavity processing processes of the inner shape, and then perform the shape processing process. The process connection of the process of the same positioning, clamping method, or the process of the same knife CNC processing is carried out to reduce the number of repeated positioning times, and the number of times and the number of times the sword is changed. Multi -processes performed in the same installation should be arranged first that the rigidity of the workpiece is destroyed.
