| Abstract: | When cutting the curve for welding groove for multi-pipe intersection with numerical control,the cutting position of the curve and its cutting vector are discontinuous.Aimed at this problem,a mathematical model for torch posture control of numerically controlled curvilineal cutting of multi-pipe intersection groove was given out and a smoothing algorithm with a third-order spline curve was investigated,so that the computer block diagram was obtained for its implementation.The feasibility of this algorithm w... |
