基于XML的CAPP产品结构设计与实现

Design and Implementation of CAPP Product Structure Based on XML

针对传统CAPP产品结构方案的不足,提出了基于XML的产品结构解决方案,分析了XML在树型结构表达及非结构化数据处理方面的优势。结合具体的焊接工艺CAPP系统,介绍了基于XML的产品结构信息描述、操作,图元文件在XML文档中的处理及XML文档的数据库存储等关键技术。

Aim at the demerits of solution tor traditional CAPP product structure, a new solution of CAPP product structure based on XML is presented. And, the merits of XML in expressing tree structure and processing non-structure data is analyzed. The description and operation of product structure information based on XML, process of metafile in XML document and storage methods of XML document in relational database are introduced in the implementation of an actual welding process CAPP system.
