摘要
特征建模及信息提取是CAD/CAPP/CAM集成的关键技术之一.本文基于成组技术和并行工程的基本原理通过回转体零件对其特征建模方法进行研究.以AutoCAD2000为操作平台,在VisualLISP集成开发环境下进行二次开发.结果表明在生成零件图的同时能提取CAPP所需的几何信息和工艺信息,解决了CAD/CAPP/CAM系统中信息共享与交换问题,对先进制造技术的发展具有工程实用价值.
Feature modeling including information extraction is one of the key technologies in CAD/CAPP/CAM integrated system.Following of the fundamental principles of grouping technology and concurrent engineering, feature modeling has been studied for revolving parts and redeveloped with AutoCAD2000 as the platform under the Visual LISP environments. The results show that being geometrical information and process information with part features can be extracted while a part drawing is being formed,and that the problem of sharing and exchanging information in CAD/CAPP/CAM system is solved.
