How to divide CNC machining processes

2023-11-22

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

1, The tool concentration sorting method is to divide the process according to the tool used, and use the same tool CNC to finish all the parts that can be completed. With the second knife, the third knife to complete the other parts they can do. In this way, the number of tool changes can be reduced, the air time can be compressed, and unnecessary positioning errors can be reduced.

2, For CNC machining parts with a lot of content, the processing part can be divided into several parts according to its structural characteristics, such as internal shape, shape, surface or plane. Generally, the plane and positioning surface are processed first, and then the hole is processed. First processing simple geometric shapes, then processing complex geometric shapes; The parts with lower precision are processed first, and then the parts with higher precision requirements are processed.

3, For parts prone to CNC machining deformation, due to the deformation that may occur after rough machining and need to be calibrated, so in general, where to carry out rough and finish machining, the process should be separated. In summary, when dividing the process, we must depend on the structure and technology of the parts, the function of the machine tool, the number of CNC machining contents of the parts, the number of installation times and the production organization of the unit. It is also suggested that the principle of process concentration or the principle of process dispersion should be determined according to the actual situation, but it must be reasonable.
