Abstract：The control system of NC drilling machine which takes the PLC as the main controller is used in drilling machine. It controls the aiguille moving from one positioning to another positioning relative to the positioning of the workpiece. The system consists of PLC, stepper motor driver, stepper motor, HMI, and so on. PLC that designed for the industrial environment specifically is an industrial control computer. It has many advantages, for example, anti-interference capability, high reliability, small size and easy programming and so on. PLC used Pulse Output Function to control the stepper motor speed, direction and distance of movement, accordingly realizing the purpose of exact orientation. HMI can be used to indicate the system’s operating state, to preserv the Filing data, but also can be to set operating parameters. NC drilling machine control system which is designed has automatic control procedures, manual control, operational control, parameter setting, and other functions.
