摘要： 为实现新的数控编程语言STEP-NC在网络化协同制造中的应用,实现网络企业间的产品信息集成和共享,使信息可以在远程、异质、异构环境下进行共享和交流,需要把STEP-NC的描述语言EXPRESS转换为XML语言.分析了EXPRESS语言和XML语言的数据类型及特点,研究了EXPRESS语言和XML语言之间的映射方法,提出了基于XML模式库和DOM接口2种EXPRESS与XML转换方法,最后给出了使用DOM接口方法进行转换的具体实现过程.为企业开展异地产品协同设计、网络化制造提供技术支持.

Abstract: EXPRESS language should be transformed into XML language when applying STEP-NC, a new NC programming language, to the cooperative manufacturing within a network for the integration and share of the product information among manufacturers, thus enabling them to share and exchange the information under remote and heterogeneous conditions. The data types and features of EXPRESS and XML languages and the mapping method between them are discussed, then two transformation techniques between them are put forward on the basis of XML schema library and DOM interface. The way of how to use DOM interfaces to implement the transformation definitely is therefore given to support technically different manufacturers to develop their cooperative product designs for networked manufacturing.
