摘    要:实体模型只提供产品低层次的几何信息而不具备高层次的特征信息,导致模型的修改十分困难,因此需要从实体模型中重构设计特征将实体模型转换为特征模型.利用分割环查找算法识别出零件模型中的布尔分割环,构建分割环关系图,根据分割环关系图识别模型中的设计特征构建零件的特征模型.最后对该方法的有效性予以验证.

关 键 词:实体模型  设计特征  分割环  特征识别  特征重构

Abstract:Solid models only provide low-level geometry information of products and do not have high-level feature information.As a result,it is very difficult to modify the solid model.It is necessary to reconstruct design features from the solid model and transform a solid model to a feature model.The cutting loop can be identified by a cutting loop search algorithm and then the relation graph of cutting loop is built.According to the relation graph,design feature can be identified and the feature model can be built.Finally,a reconstruction example is provided,which demonstrates the effectiveness of the presented method.
Keywords:solid model  design feature  cutting loop  feature recognition  feature reconstruction
