Information Model for Product Modeling

The Key problems in product modeling for integrated CAD∥CAM systems are the information structures and representations of products.They are taking more and more important roles in engi- neering applications.With the investigation on engineering product information and from the viewpoint of industrial process,in this paper,the information models are proposed and the definitions of the framework of product information are given.And then,the integration and the consistence of product information are discussed …
