In the production process, those processes directly related to the transformation of raw materials into commodities are called non-standard parts custom machining technology processes. It includes blank making, workpiece machining, heat treatment, quality inspection and machine assembly. In order to ensure the normal progress of the technical process, the production of tools and fixtures, and the adjustment and repair of machine tools are attributed to the auxiliary process. What is the principle of custom machining of non-standard parts?

The general principle of the reasonable arrangement of the CNC Machining and cutting process of non-standard parts is the front work needs to be fully prepared for the latter work, lay the foundation, and provide good services.

In the process of CNC machining of non-standard parts and CNC Metal, the foundation is the most important, and the same is true for the machining of precision mechanical parts. It is often the first to produce and process the fine datum, and then change the fine datum to position the production and process other surface layers.

For box Precision Machined parts, the main hole is usually used as the rough reference to produce the machining plane, and then the plane is used as the fine reference to produce the machining hole system; for shaft parts, the outer circle is generally used as the rough reference to machine the center hole, and then the center hole is used as the rough reference. Precision benchmark production and processing of outer circle, end face and other surface layers.

When rationally arranging the sequence of CNC machining for custom machining of non-standard parts, the rough machining of each surface layer should be centrally and reasonably arranged first, semi-finishing should be reasonably arranged in the middle according to the needs, and finally finishing and finishing should be arranged reasonably. For workpieces with high precision requirements, in order to reduce the influence of the deformation caused by rough machining on the customized finishing of non-standard parts, usually roughing and finishing should not be completed continuously, but should be completed in stages with moderate intervals.
