应用几何学的理论方法，并结合生产实际对形体相贯问题进行理论和实践研究，得出了柱锥相贯薄壁类零件相贯线上特殊点的计算方法、展开下料的通用计算公式及实用的下料方法。
Applying the geometrical theoretical method and combining with the practical production, the theoretical and practical research on the problem of the intersection of body shape is carried out. The calculation method of the special point on the intersecting line of thin-wall parts with cones is deduced, and the general formula And practical feeding method.
