Abstract: | Surface blending is very important in geometric modeling and is widely used in product design and manufacturig. This paper has a comprehensive discussion in surface blending with constant/variable radil, including the generation of rolling-ball blending between a curve and a surface, rolling-ball blending between two surfaces at a given contact curve, sliding-circle blending between two surfaces, etc. All those algorithms developed have been put into the commercial CAD/CAE/CAM software system-CAXA-ME and greatly enhanced its modeling ability |
