基于STEP的CAD/CAPP集成系统的特征造型

Characteristic Model of CAD/CAPP Integrated System Based on STEP

介绍一种基于STEP并充分考虑形状所具有的工艺特性和制造特性的CAD/CAPP集成系统特征造型。把特征定义为应用环境下的几何与属性集,并运用AutoCAD的二次开发工具Autolisp实现其特征造型。

This paper introduces a STEP-based characteristic model of CAD/CAPP integrated system,which fully considers the character of craft and manufacture.The feature is defined to geometry and property together,its characteristic model is presented by using the secondary development tool Autolisp.
