摘要: 针对维特征模型,应用基于语义的特征识别方法实现加工特征的识别。结合实例介绍了21〖〗2维特征的生成语义和加工语义,在特征转换过程中不同语义邻接特征的分离,以及相同语义特征转换而成的加工特征之间的结合。最后介绍了基于特征语义的特征识别的流程。

Abstract: 2D feature models, machining features can be recognized by means of feature recognition based on semantics. The generation semantics and engineering semantics of 2D features, the separation of adjacent features with different semantics and the composition of the features with the same semantic features are explained with samples. And the flowchart of feature recognition based on feature semantics is shown in the end.

Key words: feature recognition, features semantics, feature transition, machining model
