基于可拓学的零件工艺实例描述与修改方法研究

Part Process Case Description and Modification Method Study Based on Extenics

通过对零件工艺实例信息的分析,构建了用于描述实例的基元模型;对实例模型的修改操作进行了分类,提出了修改的流程;并运用可拓分析与变换原理,提出了各项修改操作的方法,从而解决了基于实例推理技术的工艺设计过程中的零件实例描述与修改问题。最后,通过例子验证了以上方法的可行性。

With analysis of the part process case＇s information, the element model which is used to describe the part process case is established in the essay. And the process of the model＇s modification is proposed, after classifying the modification operations of the model. Also, all operations＇ methods for the case model modification are put forward, based on extension analysis and extension transform theory. Thus, the problems of description and modification the part process case in the process designning based on the CBR are sloved. Finally, an example shows that the methods are valid.
