2.
The design cases are stored by relational database . the similar case can be obtained from the database by direct code retrieving and similarity coefficient computing . different overwrite mechanisms are used to overwriting different case database , for example , deriver overwriting for working parts , cbr for standard parts and feature - modeling for non - standard parts 通过对冲裁模设计过程的分析，将设计方案组织成冲裁件及对应的冲裁模实例库，采用简单实用的编码法对实例进行编码；利用关系数据库存储实例，直接通过对编码的检索和相似性系数的计算得到相似实例；采用派生改写法改写工作零件，基于cbr的数据库改写标准件，特征造型法改写非标准件。
