According to the different process, the process benchmark of precision parts can be divided into casting, forging, stamping, welding, heat treatment, machining, assembly and so on. Precision parts processing process generally refers to the whole part of the CNC machining and machine assembly process, and other such as cleaning, inspection, equipment maintenance, oil seal and so on are just auxiliary process. Turning method changes the surface properties of raw materials or semi-finished products. This process is called numerical control machining process, and the numerical control machining process is the main process in precision parts processing industry.
The following details about CNC precision parts processing process benchmark
(1) Positioning datum is the positioning datum used by the lathe or fixture when the CNC lathe is processing.
(2) Measurement datum, which usually refers to the standard of size or position to be observed during inspection.
(3) Assembly datum, which we usually refer to the position standard of parts during assembly process.
