摘　　要：CAx信息表达方式的不统一导致了"信息孤岛"的出现,不利于CAx系统间数据、功能的集成.NGGPS为CAx系统间实现数据和功能的统一提供了良好的基础.为此,文中提出利用数学逻辑建模方法依据NGGPS理论构建应用NGGPS的数学逻辑模型.采用UML对基于NGGPS的CAx集成系统进行分析与建模,使用面向对象程序设计方法实现应用NGGPS的CAx集成系统的信息功能模块.实践表明,所设计的基于NGGPS的CAx集成系统信息功能模块具有结构清楚、信息及功能完备、实现容易的特点,且具有良好的扩展性、移植性,方便实现网络化的数据共享与协同操作.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.
