摘要
分析了常用螺旋形体造型方法的缺陷。根据圆柱螺旋面的形成原理,从研究圆形螺旋曲面数学建模入手,建立了各种截面形状的螺旋曲面造型的数学模型,并在AutoCAD中给出了基于Visual-LISP的各种管状螺旋曲面的CAD绘图方法与技巧。最后,讨论了圆形截面螺旋曲面上螺旋线的形成与CAD绘图。
It analysis the defects of commonly used methods on helical-body modeling, and establishes mathematical modeling of helical curved surface about all kinds of section shape based on the forming principle of helicoid and studying mathematic modeling of helical curved surface of circle shape .The method and skill of CAD drawing about all kinds of tubular are given , one of which uses AutoLISP language in AutoCAD. Fanally , the forming and CAD drawing of Helix on helical curved surface about circle shape are di...
