What are the requirements for the division of CNC machining procedures?

2022/07/22

CNC machining in the division of the process must depend on the parts of the structure and process, CNC machining center machine tool function, parts of the number of CNC machining content, the number of installations,s and the production organization of the unit to master flexibly. In addition, it is suggested that the principle of process concentration or process dispersion should be determined according to the actual situation, but it must be reasonable. The process division can generally be carried out in the following ways:


 1, tool concentration sequencing method

CNC machining in the division of the process must depend on the parts of the structure and process, CNC machining center machine tool function, parts of the number of CNC machining content, the number of installations,s and the production organization of the unit to master flexibly. In addition, it is suggested that the principle of process concentration or process dispersion should be determined according to the actual situation, but it must be reasonable. The process division can generally be carried out in the following ways:


2,in order to process parts

The structural shape of each part is different, and the technical requirements of each surface are also different, so when processing, its positioning mode is different, so it can be divided according to the different positioning modes of the process.

 

For processing, a lot of parts can be divided into several parts according to their structural characteristics, such as inner shape, shape, surface, or plane. Generally first processing plane, positioning surface, after processing hole; Process simple geometric shapes first, and then process complex geometric shapes; Machining the parts with lower accuracy first, and then machining the parts with higher accuracy requirements.


3, to rough, finishing classification method

According to the machining accuracy, stiffness and deformation of parts and other factors to divide the process can be divided according to the principle of rough and finish processing, that is, rough processing first and then finish processing, at this time can be processed by different machine tools or different tools; For parts prone to machining deformation, due to the deformation may occur after rough machining and need to be shaped, so generally speaking, were to carry out rough and finish machining to separate the process.
