摘　　要：根据CIMS信息集成的需要,提出了基于PDM环境的信息集成框架;探讨了在PDM集成框架下CAPP从PDM数据库中获取产品属性信息、产品结构信息和产品图形信息的方法;研究了CAD/CAPP/PDM系统中数据文档的格式和类型,并将不同格式的文档划分为无格式文档和有格式文档。据此,阐述了CAPP生成的工艺文档、工艺要素及属性信息在PDM框架下进行CAPP数据存储的一个模型和应用实例,从而实现CAPP和PDM的数据交换与信息集成。According to the demand of CIMS information integration, the information integration framework based on PDM environment is put forward. The methods of CAPP system getting products attributes information, products structure information and products graphics information from PDM databases are discussed. The formats and types of CAD/CAPP/PDM data documents,which are divided as formatted documents and unformatted documents, are researched. Accordingly, a method and its example are presented, which are concerned with PDM system storing and managing the process documents, process elements and its attributes information produced by CAPP system. Thus the data exchange and information integration are realized.
