【摘要】 随着计算机辅助设计与制造(CAD/CAM)技术和Internet的发展,为了解决各不同系统之间CAD模型数据信息的交换问题,基于XML(ExtensibleMarkupLanguage)构架,提出了一种新的机械图描述语言XPgML(ExtensiblePart-graphicsMarkupLanguage).在对机械图分析的基础上,利用统一建模语言(UML)ROSE工具建立了机械图数据模型,并对机械图构件的元素和属性进行编制,为实现网络化设计、加工和交流打下了基础.更多还原

【Abstract】 Following the development of CAD/CAM and Internet , for the sake of exchanging different CAD models’ data among different systems , it’s necessary to bring forward a new machine-graphics describing language.We call it XPgML (Extensible Part-graphic Markup Language ). Based on analysing machine-graphics , this paper sets up data model by UML(Unified Modeling Language) and ROSE, authorized elements and attributes of machine-graphics. And these are all the groundwork for Internet design, machining and intercommunion.更多还原
