How to divide the CNC machining process?

CNC machining, also known as CNC machining, refers to the machining performed with CNC machining tools. Because CNC machining is controlled by computer after programming, CNC machining has the advantages of stable machining quality, high machining accuracy, high repeatability, complex profiles, and high machining efficiency. In the actual processing process, human factors and operating experience will affect the processing quality to a large extent.

The division of CNC machining processes can generally be carried out in the following ways:

1. The tool centralized sorting method is to divide the process according to the tools used, and use the same tool to CNC process all the parts that can be completed. Then use other knives to finish other parts that they can. This can reduce the number of tool changes, compress the idle time, and reduce unnecessary positioning errors.

2. For parts with many CNC machining contents, the machining part 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 shape is processed first, and then the complex geometric shape is processed; the parts with lower precision are processed first, and then the parts with higher precision are processed.

3. For the parts that are prone to CNC machining deformation by the rough and fine CNC machining sequence method, due to the possible deformation after rough machining, the shape needs to be corrected. separate. In summary, when dividing the process, it must be flexibly grasped according to 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 organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must be reasonable.
