Research on integration of multi-style knowledge in digital design process of product

The state of art of the knowledge reuse and the categorizing of design knowledge are discussed in this paper. The concept of “multi-style knowledge” is proposed to describe the different knowledge during the design process of digital product. In addition, the method of knowledge fusion based on domain ontology is given after the study on knowledge integration. At last, the application of this method is interpreted by case study via knowledge reuse in the digital design process of a screw-rolling machine.
