Abstract
This paper studied the design of PLC electrical control system of CNC machine tool. The design program of the electrical control system is established according to the requirements. The parameters of all electrical components are determined through calculation of electric load for selection of electrical equipment and wires. Then the design of power supply and distribution of the electrical control system is described in detail, and the design of the electrical control system of main equipment is studied. This paper focuses on the design of spindle, feed axis and module. In addition, this paper summarized the design of the electrical control cabinet, wiring, installation and commissioning of electrical equipment, inspection of the machining effect after installation and the control system. The entire CNC machine tool electrical control system is designed.
