摘要
标准件库已成为计算机集成制造系统不可缺少的部分 ,本文探讨了利用通用关系数据库设计标准件特性参数库的方法 ,给出了一大类标准件特性参数库的E_R模型 ,分析了标准件信息检索系统和参数化几何图形程序库的设计方法 ,并在AutoCAD上开发了实用的应用系统 .
The standard part library has become a necessary part of CIMS. The design methods of standard part library using relation database were discussed in this paper. The E_R Model of Characteristic Parameter Library for One Class of Part was given and general methods for programming searching system and parametric geometry graphics were analyzed. An application system on AutoCAD was developed.
