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:
1. The CNC processing of the upper process cannot affect the positioning and clamping of the launch process. Those who are interspersed with general machine tool processing processes must also be comprehensively considered.
2. Give the internal cavity processing processes of the internal cavity of the inner shape, and then perform the shape processing process.
3. It is best to connect to the same positioning, clamping method or the same knife CNC processing process to reduce the number of repeated positioning times, and the number of times and the number of times the sword is changed.
4. Multiple processes performed in the same installation should be arranged first that the rigidity of the workpiece is damaged.
