摘　　要：组合夹具图形库通常不能跨平台使用,限制了其在网络上的数据交换和协同。利用可扩展标记语言(eXtensi-ble Markup Language,XML)对基于CSG(Constructed Solid Geometry)建模的组合夹具图形库中图形信息进行了描述,实现了组合夹具图形信息和XML文档信息的数据映射,验证了用XML表示组合夹具图形的可行性,为实现组合夹具图形数据在异构CAD系统上的数据交换和基于XML的组合夹具图形库系统的网络传输与共享奠定了基础。Usually the graphic database of combination fixture can not be used in different platforms, thus limited its data exchange and cooperation in network. Using the eXtensible Markup Language （XML） to carrying out description on the graphic information in the combination fixture graphic library based on CSG modeling, thus realized the data mapping between the graphic infor- mation of combination fixture and the XML document information. The feasibility of combination fixture graphs expressed by XML was testified, thus laid a foundation for the data exchange of the graphic information of combination fixture in different structured CAD system and for the network transmission and sharing of the combination fixture graphic library system based on XML.
