Sequence of CNC precision machining operations

Sequence of CNC precision machining process

CNC precision machining, also known as CNC machining, refers to the machining performed by CNC machining objects. Because CNC machining is controlled by computer after programming, for this reason, CNC has the advantages of stable quality of preparation, high machining accuracy, high repeatability, and can process complex surfaces and high processing efficiency. In the actual processing process, human factors and operating experience will greatly affect the final processing quality. Below, Wofu will explain the sequence of CNC precision machining procedures to everyone.

The tool intensive sorting method is to use the same tool to CNC precisely machine all the parts that can be realized according to the tools used. In other places where they can achieve with the second knife, the third. This can reduce the number of tool changes, compress the idle time, and reduce redundant positioning errors.

According to the machining part sequence method, the parts that are allowed in CNC precision machining can be sorted according to their order. The organizational feature divides the processing surface into several parts, 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 pattern is processed first, and then the complex geometric pattern is processed; the parts with lower precision are processed first, and then the parts with higher precision are processed.

The rough and fine CNC precision machining sequence method is used for parts that are prone to CNC precision machining deformation. Due to the possible deformation after rough machining, it needs to be corrected. Therefore, generally speaking, rough, For finishing, the process should be separated. In general, when separating processes, it is necessary to flexibly grasp the organization and craftsmanship of the parts, the benefits of the machine tool, the content of the CNC precision machining of the parts, the number of installations and the production organization state of the unit. It is also recommended to select the principle of intensive process or the principle of process evacuation, which should be confirmed according to the detailed environment, but it must be reasonable.
