This paper studies the application of four-frequency laser in electric collaborative control system.The system combines four-frequency laser with the functional characteristics of electric system and the processing requirements of machine tools.The electric collaborative control system is designed by using collaborative control scheme.The system initializes the parameters of four-frequency laser through industrial computer,transmits the laser beam which can adjust the coordinate data of motor to the numerical control system,and the numerical control system transmits the laser beam through the laser optical scanning head switching and adjusting motor;cooperative control unit receives processing data and control commands sent by industrial computer to optimize processing scanning.Industrial computer,numerical control system and cooperative control unit cooperate with each other through four-frequency laser.The analog output of four-frequency laser sensor in the system is incremental,and the laser control function is added to the power supply.The focal length measurement is realized by feedback of the measurement data from fourfrequency laser sensor and the movement of the axis of CNC machine tool system.The experimental results show that the machining error of the electric cooperative control system based on four-frequency laser is less than 0.1 mm,the energy consumption is low,the quantity of heat and exhaust gas is small,and the control voltage effect is good.
