基于XML的工艺信息管理系统研究开发

围绕产品工艺设计的相关过程，在分析用户权限管理、工艺文件生成、工艺资源管理和工艺签审流程基础上，提出了一种基于XML数据描述的CAPP软件系统开发，将工艺数据的访问权限细化到卡片中的列或格。系统采用产品工艺文件树和资源树的形式，对工艺文件的生成进行统一有效的管理。通过对用户权限的划分，将产品数据、设计活动、相关人员和应用工具组织起来，达到对工艺设计过程进行有效管理的目的。

Study and Development of Process Information Management System Based on XML

Based on the analysis of roles and relative rights, process cards producing, process resource management and process authorization about the procedure of process planning, a CAPP system based on XML technology is presented in this paper, which is able to control the access to different tables in a process card. The concept of process document tree and resource tree is introduced and incorporated into the traditional theory of process planning management. The definition of tasks and relative rights can organize product data, product design, and the application well, which makes the management of process planning in CAPP system possible.
