基于描述逻辑的数控铣床加工工艺知识库检索

Knowledge Base Retrieval of Processing Techniques of CNC Milling Machine Based on Description Logic

数控铣床加工工艺知识库能够辅助操作人员进行操作决策,为了提高检索知识库的准确性和有效性,提出了一种基于描述逻辑的知识库检索方法,利用描述逻辑对检索需求和知识进行描述,消除语义的模糊性和二义性,通过实例说明该方法能够准确和有效的检索加工工艺知识。

Knowledge base retrieval of processing techniques of CNC milling machining can be auxiliary operation personnel of operation decision. To improve the accuracy and efficiency of the knowledge base, a retrieval method of knowledge base based on description logic is proposed. Using description logic to describe the retrieval demand and knowledge, semantic fuzziness and ambiguity are eliminated. Example result shows that the proposed method can accurately and efficiently retrieve knowledge of processing techniques.
