The solid modeling of the fillet on the intersection line of two cylinders

Abstract

偏置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.经分析,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.
