The sequence of CNC Machining industry for precision parts is crucial as it ensures the quality of precision parts. If a process is wrong, it will cause significant losses, and in severe cases, it may require rework. So what is its sequence (process)?
The sequence arrangement of CNC machining of precision parts should be based on the structure and rough condition of the parts, as well as positioning, centering, and fixture considerations. The key is that the rigidity of the workpiece cannot be damaged. Therefore, the milling process of the previous process should not affect the positioning and clamping of the next process, and other CNC machining processes interspersed in the middle should also be considered.
In the same clamping process, the process that causes minimal rigidity damage to the workpiece should be arranged first. According to the structural characteristics of precision parts, the processing part can be divided into: inner cavity shape, curved surface plane. First, process the inner cavity, then process the positioning surface into a flat surface, then process the curved surface, and continue to process the hole. This can reduce the number of tool changes and clamping, save time, and reduce errors. First, it is processed into simple geometric shapes, with low precision rough machining, and then processed into complex geometric shapes with high machining accuracy. Perform fine processing.
