摘要
本文在分析自由过渡曲面设计方法的基础上，对多曲面间光滑自由过渡曲面的设计方法进行了研究，提出了多边域自由过渡曲面的分割拼接设计方法，由于采用了Ｂｅｚｉｅｒ曲面模型，图形数据符合ＩＧＥＳ标准，可和商品化ＣＡＤ／ＣＡＭ系统进行数据交换，因而可解决多曲面间的光滑自由过渡曲面的设计和数据加工问题。
On the basis of analyzing the blending between two surfaces,the method of smooth free blending between surfaces is studied in the paper.The blending surface,which connects mulitive surfaces smoothly,is developed by dividing Nsided surface into rectangular patches. With the adoption of the Bezier patch model,the data of the blending surface can transform to CAD/CAM system,with which NC code generate.
