The Solid Modeling of the Fillet on the Intersection Line of Two Cylinders

圆柱体相贯线上的圆角表示方法是CAD和计算机辅助设计中众所周知的难题。所有的CAD／CAM软件都没有这一功能。多数使用者用各种各样的近似方法。本文找到了严密的精确的设计和几何造型方法。可用于大型铸锻件CAD 和计算机辅助设计。

The solid modeling of the fillet on the intersection line of two cylinders is a difficult problem in CAD and CAM, all the soft wears have no such function. Most designers have to use various kinds of method. This paper finds a correct way for design and geometric modeling, and finds a precise method to generate the fillet surfaces. Can be applied to the CAD and CAM of machinery parts.
