摘　　要：针对机床导轨设计过程复杂和效率低的问题,提出了一种基于CBR的导轨设计方法.首先构建了机床导轨智能设计系统框架;然后研究了机床导轨智能设计关键技术,即案例推理与规则推理流程、导轨本体构建和基于本体概念相似度的案例检索算法;最后结合机床导轨设计实例,验证了此方法能高效地完成导轨的变型设计和系列化设计.The existing traditional approaches for the design of machine tool guide rails have the disadvanta‐ges of complicated process and low efficiency .In this paper ,we propose a method for the design of machine tool guide rails based on CBR （case‐based reasoning） to assist design .First ,a framework of intelligent de‐sign for the design of machine tool guide rails is proposed .T hen ,key technologies of intelligent design for the design of machine tool guide rails are studied ,including flow of CBR and RBR （rule‐based reasoning ） , construction method of rail ontology and case retrieval algorithms based on ontology conceptual similarity . Finally ,design cases of machine tool rails are analyzed .Case studies have proved that rail design based on CBR is a good solution to the variant design and serial design of rails .
