Abstract: To support the applications of the tabular layouts of article characteristics (SML) technology in the product design, process, manufacturing and measurement, the integration technology of Computer Aided Technology (CAx) and Product Data Management （PDM） system was studied based on the SML. An integrated product information model and the system integration architecture of CAx/PDM based on SML were brought forward. And a prototype integration platform was also developed. Finally, an application example of steam turbine rotor was provided to validate the feasibility of the system.

Key words: tabular layouts of article characteristics, computer aided technology, product data management, system integration, integrated product information model, steam turbine

摘要： 为支持事物特性表技术在产品设计、工艺、制造、测量等阶段的应用，深入研究了基于事物特性表的计算机辅助技术系统与产品数据管理系统的集成关键技术，提出了一种统一的基于事物特性表的集成产品信息模型和计算机辅助技术/产品数据管理系统集成框架，并在此基础上构建了集成平台。最后，以汽轮机转子为应用对象，对系统进行了应用验证。
