Simulation and character recognition for Plate Marking Machine

This paper focus on marking process simulation and product identification of Plate Marking Machine, which are the two basic process of product life trace. The system construction, working principle and marking process are introduced, and the virtual simulation can run step by step and be saved as bitmap file or stream file. A new Vector arithmetic is introduced in character recognition with standard recognizing library instead of special library which needs a lot of training process. In vector arithmetic new x-y axis are built with least-squares method which estimates the measurable step units. The simulation and character recognition give a better resolution of marking machine for BaoSteel especially in product life trace, which has good actual performance.
