摘要
对圆锥弯管的下料问题进行了研究,从理论上给出了满足某些预定条件的连接时,圆锥弯管展开图中的曲线方程,从而为这类问题的合理下料提供了方便而精确的方法.
Study on the question of cutting stuff of cone bend pipe has been made. In theory, curve equation on the developed drawing of surface line of cone pipe has been worked out when some cormctions meet some predeterminod conditions. thus providing a convenient and exact method for reasonable cutting material.
