Part of CNC control can be divided into digital control and sequence control two parts. This paper describes the basic CNC composition, working principle, classification and their respective characteristics. And the PLC for nc machine tools have also been introduced in detail, the PLC in the control nc machine design. Then Z3040 with radial drilling machine as an example, describes its design process, including control system circuit analysis, Z3040 radial drilling machine principle diagram, using PLC programming control of machine.
