In view of the problem of weld grinding in the welding process of high speed EMU bogie frame,intelligent welding technology for different types of welds is studied with advanced intelligent manufacturing technology. The system can compare the physical appearance with the control system model in real time through the visual inspection system,and plan the grinding path and the cutting feed parameters,Through the design of intelligent grinding system to achieve high-speed EMU bogie frame of various types of weld grinding,in order to achieve the goal of improving production efficiency,enhancing product quality and reducing labor intensity.
