柱锥相贯薄壁类零件展开下料的研究

Theoretical Study on Material Unfolding and Cutting out of Thin-wall Spares Intersected in Cylinderal and Cone Shapes

针对机械生产中十分常见而又极难解决的形体相贯问题，应用空间解析几何学和画法几何学的理论方法进行研究，得出了柱锥相贯薄壁类零件相贯线特殊点的计算方法和下料展开的通用计算公式与实用的下料方法。

Apply the space analytic geometry and scriptive geometry to obtain the methodof calculating the special points of intersected lines, the calculation formula of materials unfolding and cutting out and the method of material cutting out in practice of thin-wall sparesintersected in cylinderal and cone shapes in accordance with the common and difficultly solvedproblems of shapes intersected in mechanical production.
