【摘要】 CAPP是CIMS中一个重要的组成部分,它不仅是连接CAD子系统和CAM子系统的纽带,而且与CIMS中的MIS,MRP等子系统都有着十分紧密的联系。因此,CAPP已经成为现代制造技术中的一个重要研究领域。多年来,CAPP技术在理论上有所创新和突破,但其应用范围仍具有较大的局限性。现有的CAPP系统大都是面向某一类零件(如箱体类零件,回转体类零件等)的专用系统,只能应用于特定的某个企业;并且其中的一些系统不能在网络环境中运行,无法保证CAD和CAPP所需数据的一致性和完整性。因此,在加强对CAPP系统的理论研究同时,进一步推进CAPP的实用化和通用化,具有重要的现实意义。 本文概述了目前国内外CAPP的发展现状和存在的问题,提出了本文研究的内容。本着实用化、通用化、框架化的指导思想,利用先进的计算机技术,综合现有CAPP系统的优点,结合纺织机械行业工艺设计的具体情况,研究和开发了基于C/S(客户/服务器)结构,以整个产品为应用对象,以各种数据库为核心,以面向对象进行数据定义和交互式设计为基础,辅以各种应用支持工具,能广泛应用于纺织机械各种不同层次和类型的企业或企业的不同工艺部门的集工艺设计与工艺管理为一体的交互式的CAPP系统。更多还原

【Abstract】 CAPP is a major component in CIMS. It not only acts as a tie which joins CAD and CAM systems together, but also keeps close links with other sub-systems such as MIS, MRP, etc. in CIMS. Therefore, CAPP has been regarded as an important research field of modern manufacturing technology. For many years, a lot of new theories and methods have been put forward in this field, but the application coverage of CAPP is still very limited. In fact, almost all of the CAPP systems are developed as specialized system for special parts (such as polyhedrons, cylinders), and some of them cannot be used under network circumstance, so the data consistency and integrity by CAD and CAPP cannot be assured. Thus there is immediate significance in further promoting the practicality of CAPP technique while reinforcing the study of CAPP theories.In this dissertation, the current achievement of domestic and worldwide research and existing difficulties of CAPP is summarized. Based on the principle of practicality and universality, the careful analysis and study of this system has been given in this thesis in combination with the process planning of textile machine. This system is designed to be Client/Server architecture and utilizes series advanced computer techniques; also, it combines the experience of several kinds of CAPP systems having developed together. This system makes the whole product applied subject and several database as the core. Through utilizing a variety of supporting tools, it can be used widely in the framework system of interchanging CAPP in all kinds of enterprises at different levels or different process sectors that combine the process design with information management as a part in an enterprise.更多还原
