CNC machining, also called CNC machining, refers to machining with CNC machining tools. Because CNC machining is programmed and processed by computer, CNC machining has stable processing quality, high machining accuracy, high repeatability, complex machining surface and high machining efficiency. In the actual processing process, human factors and operational experience will affect the processing quality to a large extent. Let's take a look at it:

First, how to divide the cnc processing process?

The division of the CNC cnc machining process 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 cnc according to the dividing process of the used tool. In the other parts that can be completed with the second knife and the third. This reduces the number of tool changes, compresses the dead time, and reduces unnecessary positioning errors.

2, the processing part sorting method for the cnc processing a lot of parts, according to its structural characteristics, the processing part is divided into several parts, such as inner shape, shape, 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 complicated geometric shape is processed; the lower precision part is processed first, and the processing precision requirement is higher.

3, the coarse and fine cnc processing and ordering method for the parts that are prone to cnc processing deformation, due to the deformation that may occur after roughing, need to be shaped, so generally the rough, fine processing must be the process separate. In summary, when dividing the process, it must be based on the structure and process of the part, the function of the machine tool, the amount of CNC cnc machining content, the number of installations and the unit's production organization status. It is also 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.
