【摘要】 在现代机械制造业中，Computer Aided Process人Planning(计算机辅助工艺设计)具有重要的理论意义和广泛、迫切的实际需求。CAPP系统的使用，不仅可以大大提高工艺设计的速度和质量，而且可以提高工艺设计的规范化和标准化的程度。 本文在阐述了目前CAPP技术现状及趋势的基础上，分析了现有CAPP系统所存在的问题，结合企业对CAPP系统的基本要求，提出基于实际的工具型CAPP系统。系统开发以派生式原理为基础，具有工具型模式特点，为用户提供各个工具子系统，研究了资源数据存储和管理模式，建立开放式工艺资源数据库管理系统，实现了工艺资源数据的动态管理；在此系统的支持下，实现交互式工艺设计；提出检索式工艺设计和基于实例的工艺设计方法，并对其中关键技术进行分析研究，提出实现方案；兼于系统开发针对具体企业，其产品以齿类零件为主，因此系统以齿轮加工工艺设计为示例，并建立了齿轮加工专用刀具的设计模块，在工艺设计过程中可以调用该模块对刀具设计参数进行设计。更多还原

【Abstract】 In the modern mechanical manufacturing , computer aided process planning (CAPP) is of important theoretic significance and is required pressingly and extensively.Making use of CAPP system not only can greatly improve the quality and speed of process design , but also enhance the degree of standardization and normalization of process plan.On the basis of elaborating the current situation and tendency of CAPP technology , problems that present CAPP system faced are analyzed in the paper. Combined with basic demand of CAPP system required by enterprise , a kind of tools CAPP system based on real circumstances is proposed. The system is developed based on principal of variant and is of characteristic of tools model which provide a lot of tools subsystems. Storage and management model of resource data is researched and an open data base management system of process resource is building. Dynamic management of process resource data is achieved. Searching mood method of process design and method of process design based on real example are proposed. Key technology of them is researched and realizing plan is provided. In view of the fact that the system is developed for specific enterprise whose products are of class of gear,process design of gear is provided as example in the system and design module of special cutter for machining gear is built. Cutter parameters are designed by calling the module in the process design.更多还原
