    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.
