There are several ways to divide the CNC machining process?(1) Dividing the process according to the positioning method of parts mounting: the shape of each part is different, and the technical requirements of each surface are also different.

Most of the actual machining errors are caused by the irrational processing technology. In ensuring the basic processing technology (such as "roughness first, then precision, first surface then hole, first large surface, then small surface" or fixture use " Reduce the number of clamping, try to use the combination of fixtures and other basic processing details ", to minimize the processing errors caused by iron filings on aluminum parts, because aluminum parts are very soft, and the excluded iron filings can easily cause processing errors on aluminum parts. . For example, in FANUC or Central China machining centers, use the G83 command to make deep holes as much as possible so that iron filings can be discharged instead of the G73 command.
