| 摘 要： | 圆角过渡特征的识别在特征识别与设计特征重构方面有着非常重要的作用. 本文提出了一种基于设计意图推理的圆角过渡特征识别方法. 该方法首先对圆角过渡面几何形状进行识别，然后捕捉一般圆角过渡特征的设计意图，并识别过渡特征、推理出过渡特征之间的先后顺序，用有向无环图描述过渡特征之间的关系，对有向无环图进行拓扑排序得到过渡特征的一个线性序列. 文章最后给出了实例来证明该方法的有效性.

| Abstract: | The identification of blend feature plays a very important role in the feature recognition and reconstruction of design features. In this paper, a method of blend feature recognition based on design intent reasoning is proposed. Firstly, the geometrical shape of the blend surface is identified, and then the design intention of the general blend feature is captured. The blend features are identified and their order is deduced. A directed acyclic graph is used to describe the relationship among blend features, and the sequence of blend features is obtained by topology sorting of the directed acyclic graph. Finally, an example is given to demonstrate the effectiveness of the proposed method. |
