How to divide the cnc machining process?

CNC CNC machining process division can generally be carried out according to the following methods:

1, tool centralized sequence method is to divide the process according to the tool used, with the same tool CNC machining parts on all parts can be completed. Use the second knife and the third to complete other parts that they can complete. This reduces the number of tool changes, compresses the idle time, and reduces unnecessary positioning errors.

2. For parts with many machining contents in cnc, the machining parts can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc. Generally, the plane and positioning surface are processed first, and then the hole is processed; the simple geometric shape is processed first, and then the complex geometric shape is processed; the parts with lower machining accuracy are processed first, and then the parts with higher accuracy requirements are processed.

3. For parts that are prone to cnc machining deformation by rough and fine cnc machining sequence method, it is necessary to calibrate the shape due to the deformation that may occur after rough machining. Therefore, generally speaking, the processes should be separated for rough and fine machining. To sum up, when dividing the process, we must depend on the structure and process of the parts, the function of the machine tool, the number of parts CNC machining content, the number of installations and the production organization of the unit. 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.
