摘　　要：利用基于实例推理的技术,为建立切削参数数据库提供一个有效可行的方法,即将以前切削加工积累的切削数据和经验存储在数据库中,为新的工件加工问题提供参考解决方案。建立了简洁可行的用结构化数据表示的实例描述模型,分析了实例相似度的计算问题并介绍了实例检索的具体方法,使系统的数据采集和知识更新简单易行。By applying case-based reasoning, the cutting parameter database system is developed , where cutting data and experience are stored for machining new part by technology. The case-based reasoning has presented a kind of feasible and effective method for establishing machining database system in which cutting data and experience accumulated before are stored to provide refer2ence solving scheme for machining new part by technology. A simple and feasible case model described by structured data is proposed. The calculation of case similarity is discussed and the specific method of case retrieve is introduced, the data collect and knowledge update of database system is simpler and easier.

关 键 词：切削加工 数据库 基于实例推理 相似度
