How is the CNC machining process divided?

Here, the technology relies on more than ten years of cnc processing experience to make a summary for everyone. 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 in the following ways:

1. The tool 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 on the part;

2. Two knives and a third do the rest they can. In this way, the number of tool changes can be reduced, the air travel time can be compressed, and unnecessary positioning errors can be reduced; The processing part can be divided into several parts according to its structural characteristics, such as inner shape, outer shape, curved surface or plane, etc.;

4, generally first process Plane, positioning surface, and then process holes; process simple geometric shapes first, and then process complex geometric shapes; process parts with lower precision first, and then machine parts with higher precision requirements;

5. For the parts that are prone to CNC machining deformation by the rough and fine CNC machining sequence method, due to the possible deformation after rough machining, it is necessary to correct the shape, so generally speaking, rough machining , The finishing 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 contents of the parts, the number of installations and the cost of the parts. 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.
