摘　　要：采用XML技术进行系统集成具有平台无关性和良好的可移植性,是目前实现CAPP与PDM集成的首选技术,针对现有XML工艺信息模型中无法表示工艺卡片样式的问题,提出了通过虚拟打印的方式将工艺卡片转换成PDF格式文件,并通过BASE64编码将其嵌入到XML工艺信息模型中的方法,通过该方法构建的XML工艺全域信息模型可以表示任意复杂工艺卡片样式.然后基于该模型建立了系统集成框架并给出了应用实例,该集成框架通过插件封装技术和数据交换池技术封装了PDM和CAPP系统的底层接口实现细节,保持了两系统的相对独立,具有较好的可维护性和可移植性.System integration based on XML（Extensible Markup Language） has a good portability and platform independence,and it′s the first choice to integrate CAPP（Computer Aided Process Planning） and PDM（Product Data Management）.Using XML to describe the process card content is relatively mature,but it can not manage the process style date effectively in the PDM system because different CAPP process card style structure and the treatment method are different and complex.To describe the card style date in XML process model,the technologies of converting process card to PDF format file and embedding it to XML process model by BASE64 code are proposed.Using the technologies about plug-in and data exchange pool to encapsulate the lower layer interface of PDM and CAPP,the integration framework based on the fully XML process model is established.At last,application of the integration platform is presented.The result shows that the platform has a good maintainability and portability,and it can guarantee the independence among systems.
