The division of CNC CNC processing process can generally be performed in the following methods:

The knife concentration sequential method is to divide the process according to the tools used, and use the same knife set to process the parts to complete the parts that can be completed on the part. Use the second knife and the third to complete the other parts they can complete. This can reduce the number of knives, compress the air, and reduce unnecessary positioning errors. For the processing part of the processing site, there are many parts with a lot of CNC processing content. The processing part can be divided into several parts according to its structural characteristics, such as internal shape, shape, curved or plane. Generally, process planes, positioning planes, and then processing holes; first processing simple geometric shapes, and then processing complex geometric shapes; first processing parts with lower accuracy, and then processing accuracy requirements. For parts that are prone to CNC machining deformation with coarse and refined CNC processing method. Due to the deformation that may occur after rough processing, school shape needs to be performed. In summary, when dividing the process, we must depending on the structure and process of the parts, the function of the machine tool, the amount of parts of the parts CNC processing, the number of installations and the production organization of the unit flexibly grasp. It is also recommended to adopt the principle of concentration of the process or the principle of scattered processes. It should be determined according to the actual situation, but it must be reasonable.
