CNC machining, also known as CNC machining, refers to the machining performed by numerical control. Because CNC machining is controlled by computer after programming, CNC machining requires stable quality, high machining accuracy, high repeatability, can process complex surfaces, and high processing efficiency. In the actual processing process, human factors and operating experience will affect the final processing quality to a large extent.

The distinction of CNC machining processes can generally be carried out in the following ways: The centralized method is to distinguish the processes according to the tools used, and use the same tool CNC to process all the parts that can be completed. Use a second knife and a third to do whatever else they can. In this way, the number of tool changes can be reduced, the idle travel time can be shortened, and unnecessary positioning errors can be reduced. According to the processing part sequence method, the CNC processing parts can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc. Generally, the plane and positioning surface are processed first, and then the hole is processed;

The simple geometric shapes are processed first, and then the complex geometric shapes are processed; the parts with lower precision are processed first, and then the parts with higher precision are processed. For the parts that are prone to CNC machining by the rough and fine CNC machining sequence method, due to the possible deformation after rough machining, the shape needs to be corrected. . To sum up, when distinguishing the processes, it is necessary to flexibly grasp the structure and craftsmanship of the parts, the function of the machine tool, the number of CNC machining contents of the parts, the number of installations and the production arrangement of the unit. In addition, it is advocated that the criteria for selecting process concentration or the criteria for selecting process dispersion should be confirmed according to the actual situation, but it should be reasonable.
