CNC Machining, also known as CNC machining, refers to the use of CNC machining tools for processing. Because CNC machining is programmed by the computer control processing, therefore, CNC machining has the advantages of stable processing quality, high machining accuracy, high repetition accuracy, can process complex surface, high processing efficiency and so on. In the actual processing process, human factors and operating experience, to a large extent, will affect the final processing quality.

1. how to divide the CNC machining process?

The division of CNC machining process can generally be carried out according to the following methods:

1. The tool centralized sequencing method is to divide the process according to the tools used, and use the same tool cnc to process all the parts that can be completed. Use the second knife and the third to complete other parts that they can complete. This reduces the number of tool changes, compresses the idle time, and reduces unnecessary positioning errors.

2. For parts with a lot of CNC machining content, the machining part can be divided into several parts according to its structural characteristics, such as inner shape, 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 machining accuracy are processed first, and then the parts with higher accuracy requirements are processed.

3. For parts that are prone to cnc machining deformation by rough and fine cnc machining sequence method, it is necessary to calibrate the shape due to the deformation that may occur after rough machining. Therefore, in general, the processes should be separated for rough and fine machining. To sum up, when dividing the process, we must depend on the structure and process of the parts, the function of the machine tool, the number of Parts CNC Machining content, the number of installations and the production organization of the unit. It is also suggested to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but it must be reasonable.
