Abstract:

The inconsistent expression of CAx information leads to an ＂information island＂,which block the integration of data and functions of CAx systems.As NGGPS lays a good foundation for the integration of CAx data and functions,this paper presents a mathematical logical model for NGGPS applications based on the NGGPS theory.In the investigation,UML is used to analyze and model the NGGPS-based CAx integrated systems,and the object-oriented programming method is employed to implement the NGGPS information module of CAx integrated systems.Application results show that the designed module with full-featured information is clear in structure and easy to implement,and that it helps to easily realize network-based data sharing and collaboration operations due to its good scalability and portability.
