How to divide CNC MACHINING process ?

The division of CNC machining operations can generally be carried out as follows:

(1) The tool concentration sorting method is to divide all the parts that can be completed on the part with the same tool according to the dividing process of the tool used. Use the second knife and the third handle to complete other parts that they can complete. This reduces the number of tool changes, compresses the dead time, and reduces unnecessary positioning errors.

(2) Sorting method of processing parts For parts with a lot of processing contents, the processing part can be divided into several parts according to its structural characteristics, such as inner shape, shape, curved surface or plane. Generally, the plane, the positioning surface, and the rear processing hole are first processed; the simple geometric shape is processed first, and the complex geometric shape is processed; the lower precision part is processed first, and the processing precision requirement is higher.

(3) In the rough and fine processing, the parts that are prone to processing deformation need to be shaped due to the deformation that may occur after roughing. Therefore, in general, the rough and fine machining must be separated. 

In summary, in the division process, we must pay attention to the structure and process of the parts, the functions of the CNC machining center machine tools, the CNC machining content of the parts, the number of installations and the production organization of the unit are flexible. It is recommended 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.
