First, this thesis introduces basic theory of CBR , and studies many aspects of typical part design case , such as case representation, case retrieval, retain etc. Second, regards design code as case code in order to integrate the case with geometrical and non- geometrical information, and realizes the parametric modifying function for 3D solid model in the condition of Pro/E. Third, for the purpose of making true of system's aided design requirement, this thesis brings forward to create part design knowledge base with AI language CLIPS, and integrates the rule based KB into the system; finally, collects and summarizes the knowledge of shaft,gear,sleave, and a sample with ladder—shaft is shown in order to verify the correction of theory research.

首先，本文介绍CBR技术的基础理论，并重点研究典型零件案例的表示、检索、修改等功能；其次，以零件设计编号为案例编号实现对案例的几何与非几何信息的集成，并实现了三维实体模型在Pro／E环境下的参数化修改功能；再次，从系统辅助设计功能要求出发，提出将基于规则的知识库嵌入到系统内部，用人工智能语言CLIPS建立零件设计知识库；最后，对轴类、齿轮类、盘套类零件案例知识进行收集、总结，并通过阶梯轴设计实例验证了理论研究的正确性。

This thesis expatiates on the theory and architecture and primary content of Reusable Design technology and Reusable Process Design technology, study the feasibility and practicability of some important technology about Reusable Process Design, adopt a special knowledge representation to describe reusable process design information and make use of "FenHua "to realize knowledge acquisition about fuzzy knowledge.Craft database system is the mostly important support of CAPP (Computer Aided Process Planning) system. To some extent, the essence of process design is a process that craft data is visited, used, dealt with and generated. This thesis expatiates on data base design technology. Based on the detailed analysis of the craft data"s characteristic and sort and the craft database"s component part, the author build craft database through detailed conceptual design and logical design and physical design for data base.the application and research of Web database technology becomes increasingly wide, which can make a close combination between Database technology and Web technology.

本文阐述了基于知识复用的可复用设计技术与可复用工艺设计技术的理论、体系结构与主要研究内容，研究了可复用工艺设计中的若干关键技术的可行性、实用性，采用了三表知识表示来描述工艺知识及利用"分划"的方法对灰色知识进行知识获取；工艺数据库系统是计算机辅助工艺设计系统的重要支撑系统，从某种程度将，工艺设计的实质就是对工艺数据库中工艺数据的访问、调用、处理和生成新的数据的过程，本文阐述了数据库系统设计技术，在详细分析工艺数据的特点、分类以及工艺数据库的数据库组成的基础上，通过对工艺数据库概念结构、逻辑结构、物理结构等几个方面的详细的分析与设计，建立了系统工艺数据库； Web数据库将数据库技术和Web技术很好的融合在一起，其应用研究日益广泛。
