This paper introduces a scanning laser marking system which is based on computer, and illustrates the basic controlling principle and the realizing method of software and hardware. The combination of hardware and software make data gathering , on or off laser and mirror rotating freely , all these functions enable the system orientate precisely and mark automatically. By experimental study of continuous marking and scanning marking (lattice marking), and synthetic analysis of the technologic parameters, the optimization of route and experiment method is advanced in details.In lattice marking, the points are marked through line by line scanning, obviously this means is not only time-cost but also the carving words are saw-toothed. In order to overcome these defects, this paper presents two practicable methods to optimize the marking route and marking efffect. These two method are based on the characters of lattice diagram (which characters are resembled with black-and-white image) raise the marking route pick-up algorithm, the algorithm can found mark points in the least time by ransacking the eight points nearby. By using these two methods can improve the marking effect and accelerate the marking speed dramatically.At last, the paper give the effective evaluating method for the two route optimum algorithm, the evaluating results show that the marking speed tan improve nearly one time, and meanwhile improve the marking quality. As we can see form the experimental evaluating results, the optimum methods of marking route can have an effect in the laser marking system.
