Aiming at the problem that the existing method of component matching of CNC system can not meet the needs of the user's component matching,description logic is used to describe the request of component and provide of component.Based on the classification of the components,a method of component matching based on description logic is presented.Finally,an example shows that the proposed method can effectively help users to select components.%针对现有数控系统构件匹配方法无法满足用户的构件匹配需求的问题,用描述逻辑对需求构件和提供构件进行描述,在对构件进行匹配分类的基础上,给出了一个基于描述逻辑的数控系统构件匹配方法,最后通过实例说明该方法能够合理有效帮助用户选择构件.
