基于特征设计的焊接工件造型系统

Weld workpiece model design system based on feature

摘要: 为解决机器人焊接CAD/CAPP/CAM系统的信息共享,开发了焊接工件特征造型系统。提出了焊接工件特征的概念和分类。分析讨论了焊接特征造型方法,提出将焊接工件的造型分解为工件的造型和接头造型的思想,采用三维CAD平台建立了通用工件的造型,基于该平台二次开发实现了焊接接头的特征造型。介绍了焊接工件特征造型系统设计框架,给出了接头坡口基于特征库的特征设计实现技术。

Abstract: To realize information share among CAD,CAPP and CAM,A weld workpiece model design system was developed based on feature.Conception and classification of weld workpiece feature were introduced.The design method of weld workpiece based on feature was discussed and a model of weld workpiece was divided into workpiece part and welded joint part.This workpiece model was built by 3D CAD system,design was realised by redevelopment of the CAD based on feature of welded joint.A weld workpiece model design system framework was introduced,and the design was realised and developed based on feature of groove.
