摘要
It's necessary to realize the standardization and rationalization of the knowledge representation during the milling process of Aeronautical Structural Parts. Meanwhile, It's also important to make it convenient for sharing knowledge and improve the efficiency of processing reasoning considering the intermediate status of knowledge processing. XML language is used to carry on the parametric representation of parts based on the structural features and the hierarchical representation of machining process knowledge. Besides, hierarchical representation model of knowledge is used as the carrier to derive hierarchical reasoning model of knowledge. The reasoning method of combining model with rules is proposed. The method is based on the similarity calculation to get the most typical example. According to the working procedure layer, the working step layer and the structural feature layer, working procedure, working step and structural feature are judged. Finally, the application process of a certain type of aircraft is discussed as an example.
