以回转类零件为例 ,利用基于实例的推理 (CBR)方法、专家系统方法和特征技术 ,构造了一套完整实用的基于实例的工艺路线决策方法 .构造了一种相似性系数计算公式 ,论述了新零件与实例进行比较和匹配的策略和算法 ,以及实例工艺信息筛选和实例工艺路线修正方法 .在实例抽取过程中 ,新零件与实例的匹配信息被详细记录下来 ,使得以实例抽取为基础的实例工艺信息筛选和实例工艺路线修正算法变得相对简单并易于实现 .
Taking the turning parts as an example, a set of complete and practical example-based routing decision-making methods is constructed by using instance-based reasoning (CBR) method, expert system method and feature technology, and a similarity coefficient calculation formula is constructed. New parts and examples to compare and match the strategy and algorithm, as well as examples of process information screening and instance routing method.In the instance extraction process, the matching information between the new part and the instance is recorded in detail, making the sample extraction as the basis Example Process Information Filtering and Example Routing Algorithm is relatively simple and easy to implement.
