Study of geometric model and attitude of typical workpiece welded in robot

摘要

The idea ofbuilding blockis adopted to catch the character of complex seam welding,characteristic coordinates frame of weld ing is brought up;The mathematics model of seam is built based on the re-exploit of AutoCAD.It is deduced that the projection vector of characteristics coordinate of weld and torch relative to reference coordinates.This study is very important to offline programming of arc robot in spaced welding.
