The CNC machine tool automatically processes the machined parts according to the pre-programmed machining program. We process the machining process route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions of the parts according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program list. On the control medium, it is then input into the numerical control device of the CNC machine to direct the machine to machine the parts.
