Data model for product life cycle quality control mapping with product structure geometrical model

This paper focus on the technique of learning the knowledge on the design quality and manufacture quality. The characteristic of quality control are illustrated, such as status, process, structure etc, and a lot of feature of the quality control information which consist of geometrical structure model, manufacture technique, detect, fault diagnose and data analysis were presented. Then an approach of the mapping between the product quality control information to the components geometrical model is put out, which can be implemented to optimal the product design, manufacture and assembly in quality control. Finally a prototype system was designed based on the data model.
