金属门窗capp系统的研究与开发（本科毕业论文设计）.doc

摘 要

随着电子计算机技术的发展和门窗制造业的发展，传统的金属门窗设计与管理方法已很难适应越来越激励的市场竞争，因此，开发一套具有窗型设计、型材管理、配件管理、工程管理、工艺设计等功能的金属门窗CAPP系统已十分必要。
本论文介绍了金属门窗以及国内外门窗设计软件的发展概况，并运用CAPP及软件工程的基本原理，对门窗CAPP软件开发的一般步骤和关键技术进行了分析；讨论了本系统的适用范围，进而提出了系统的设计目标和应用目标。针对金属门窗CAPP系统做了需求分析，进行系统的概要设计，并得到本系统的功能模块图和相应的数据流程图。依次对系统的数据库部分进行了概念结构设计、逻辑结构设计和物理结构设计，最后进行了系统的界面设计及代码编写，得到了金属门窗CAPP系统原型。
论文主要介绍了本课题的开发背景，所要完成的功能和开发的过程。重点的说明了系统设计的重点、设计思想、难点技术和解决方案。

ABSTRACT

With the development of computer technology and the development of manufacturing doors and windows, the traditional design and management method of metal doors and windows has been increasingly difficult to adapt to stimulate competition in the market, therefore, it is very necessary to develop a set of metal doors and windows CAPP system which has the function of Graphic designing, management profiles, fitting management, project management, process designing and so on.
The present paper introduced the metal windows and doors as well as the domestic and foreign windows and doors design software's development survey, and using CAPP and software engineering's basic principle, has carried on the analysis to the windows and doors CAPP software development's general step and the key technologies; It has discussed this system's applicable scope, then set system's project objective and the application goal. It has made the demand analysis in view of the metal windows and doors CAPP system, carries on system's preliminary design, and obtains this system's functional module chart and the corresponding data flow chart. It has carried on the concept structural design, the logical organization design and physics structural design in turn to system's database part, finally has carried on system's contact surface design and the code compilation, obtained the metal windows and doors CAPP system prototype.
The paper mainly introduced this topic's development background, and the function and development process to be completed, key explanation the key point of system design, design concept, difficult technology and solution.


Key words：Software engineering, metal windows and doors, CAPP, Process，Visual C++ 6.0
