摘　　要：基于成组技术,提出了一种面向工艺规划的零件分类与识别方法,首先,基于现有零件的工艺信息,在对传统生产流程分析法零件相似系数进行改进的基础上,利用聚类分析方法进行零件族构造;然后,采用零件族累加矩阵来构建零件族的相似性标准,并建立了基于零件族累加矩阵的零件模式识别方法,该方法把编码分类法与零件-零件族的相似系数有机结合起来,确保新零件准确、自动地归属于相应的零件族。Based on group technology, a method of process planning oriented part classification and identification is presented. Firstly, based on known parts information, improving parts＇ similar coefficients of traditional production flow analysis to build part family by classification analysis; then, using cumulative matrix of part family to build its similar standard, also to establish the method of part pattern identification based on it, this method organically connects the part coding classification with the similar coefficients of part-part family, makes sure that new parts can be precisely and automatically attributed to its corresponding part family.
