Research on NURBS Surface Modeling and Machining System

LU Tong-fu

Open publisher page 2 citations

Abstract

In this paper,a surface modeling and processing system is studied and a CAD/CAM system of surface modeling and machining is completed by taking the popular Non-Uniform Rational B-Spline(NURBS) as a mathematical model.The main techniques (elevation,kont insertion) of B-Spline are applied to system based on NURBS,many kinds of modeling(line,arc,2-degree curve,free-form curve,plane surface,2-degree surface,ruled surface,sweeping surface,skinning surface and so on) are successfully laid out.
