摘 要: 文章提出简便实用的三线拉线法新工艺, 解决传统修造船工艺长期以来无法解决的艉轴管孔外形轮廓线的精确确定问题, 使得艉轴管贯穿船体外板三维曲面的开孔实现一次性准确成形, 既提高了工作效率, 又保证了施工质量。第一次提出了“过线”和“鉴线”这两个新名词概念。 This article gives a new method of 3-line positioning,which solves the problem of accurate positioning of tail-shaft-hole profile,as had been a difficult problem in traditional ship-building for a long time. This method makes it possible for both high-effcient working and high-quality construction. The new concepts of “over-line”and “appraisal-line”are firstly mentioned in this field.
