基于样条链（环）的CAD模型过渡特征识别与抑制
Fillet Recognition and Suppression in CAD Model Based on Feature Chain（Ring）
摘要
Abstract
The paper proposed an algorithm of fillet recognition and suppression based on feature chain. Firstly, all fillets of the model were recognized. Secondly, a face-edge graph was built based on fillets, the connected subgraph was taken out successively, and the feature chain（ring） was established. According to the feature chain, the features （fillet） in the chain was suppressed. The fillets not in chain were suppressed by connected graph of minimal and with same radius. In summary, the algorithm can suppress the fillets with variable and constant radius, and the model containing non-quadric surface fillets can be suppressed well.关键词
