What factors should be considered in the selection of surface machining methods for CNC machining parts?

The machining method of the surface of CNC machining parts depends first on the technical requirements of the machined surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the parts drawing, and may sometimes be higher than the requirements on the part drawing due to technical reasons. If the benchmarks do not coincide, the processing requirements for the surface of some CNC workpieces are increased. Or because of being a fine benchmark, it is possible to impose higher processing requirements on it. When the technical requirements of the surface of each CNC machining part are clarified, the final machining method that can guarantee the requirement can be selected according to this, and the processing method that requires several steps and each step is determined.The selected CNC machining part processing method should meet the requirements of the quality of the parts, good processing economy and high production efficiency. To this end, the following factors should be considered when selecting the processing method:
1. The machining accuracy and surface roughness that can be obtained by any kind of numerical control machining method have a considerable range, but it is economical only in a narrow range. The machining precision of this range is economic processing precision. For this reason, when selecting a processing method, the corresponding processing method that can obtain economic processing precision should be selected.
2. Consider the nature of the NC machining material.
3. Consider the structural shape and size of the CNC machined parts.
4. Consider productivity and economic requirements. When mass production is large, high-efficiency and advanced processes should be adopted.
It is even possible to fundamentally change the manufacturing method of the blank, which can reduce the labor of machining.
5. Consider the existing equipment and technical conditions of the plant or workshop. Make full use of the processing method
Existing equipment, tap the potential of the company, and exert the enthusiasm and creativity of the workers. But you should also consider constantly improving the existing plus.
Work methods and equipment, adopt new technologies and improve process levels.
