How is the CNC machining process divided?

Here, Dongguan YIFENG METAL Technology will give you a summary with more than ten years of cnc processing experience. It can be said that it is an old driver in the division of cnc processing procedures.

In the metal stamping factory, it is usually seen that the division of CNC machining processes can generally be carried out according to the following methods:

1. Tool The centralized sorting 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;

2. Knives, and a third do everything else they can. This can reduce the number of tool changes, compress the air travel time, and reduce unnecessary positioning errors; Parts, the processing part can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc.;

4. Positioning surface, then machining holes; first machining simple geometric shapes, and then machining complex geometric shapes; first machining parts with lower precision, and then machining parts with higher precision requirements;

5. The rough and fine CNC machining sequence method is used for the parts that are prone to CNC machining deformation. Due to the possible deformation after rough machining, the shape needs to be corrected, so generally speaking, rough and finish machining is required. process should be separated.

In summary, when dividing the process, it is necessary to consider the structure and manufacturability of the parts, the function of the machine tool, the number of CNC machining content of the parts, the number of installations and the cost of The production organization status of the unit is flexibly grasped.

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.
