A laser flying marking system with a galvanometer scanner could be widely used as a workhorse because the moving speed of product on the workline would not be affected while being marked. A laser flying marking system, with high-speed galvanometer scanners, was set up. Two kinds of marking effects, vector style and matrix style, were realized in the system. Different motion-tracing methods, including a closed-loop feedback tracing mode and an open-loop computing tracing mode, were studied and utilized in the control software. Experimental results show that the system using the closed-loop feedback motion-tracing method has more adaptability for variable-speed applications.
