While the application of parts-library and CAD/CAPP/CAM integration system is the important measures which shorten the design cycle, improve the quality of product and reduce the cost of design and manufacturing. In the design of mechanical products, typical parts account for nearly 70% of the total mechanical parts. Cumbersome design of typical parts seriously reduces design efficiency and prolongs product development cycle. Here,study is concentrated on the parametric parts-library of typical parts and CAD/CAPP/CAM integration system, construct the parametric parts-library of typical parts and the framework of CAD/CAPP/CAM integration system, so as to shorten the cycle of product development, reduce the cost of product design and manufacturing, improve the design and manufacture level and improve the market competition of enterprises.In this paper, through analyzing UG main functional modules, the virtual parts-library technology and the development methods of the virtual parts-library at home and abroad, the key technologies and methods related to the development of virtual parts-library such as parametric design, feature modeling and database technology theories, as well as the development idea and method of parametric virtual parts-library of typical parts were studied systematically. First time put forward the concept of the?parametric virtual parts-library of non-standard typical parts. And the development ideas and methods of parametric virtual parts-library of typical parts were studied. Four categories of parametric virtual parts-library of typical parts such as shafts, gears, dishes and forks were established based on UG NX 7.5 platform by using UG/Open which is second development tools related to UG and Visual C++6.0, and the rapid design with dialog parameters inputting of non-standard typical parts was realized.And then further analyzed the application and development situation of CAD/CAPP/CAM integration system, and studied the key technologies such as parametric technology and features technology, information exchange technology, as well as integrated methods of CAD/CAPP/CAM integration such as by special data format, by standard data format and by uniform product model format. Then put forward and established the whole life cycle of product development of CAD/CAPP/CAM integration system framework. The system includes three subsystems, which are parametric design of typical parts, CAPP of typical parts and CAM of typical parts. It can be used to realize the rapid creation of four types of parametric design of typical parts and establishment of parametric virtual parts-library, the active generation of the machining process sheet of typical parts and the corresponding operation sheet, and virtual processing, virtual testing and automatic generation of NC code of typical parts. The system integrates seamlessly with UG system, and the interface of the system has good human-machine interaction. It runs fast and operates easily. It is of strongly practical value. 【关键词】典型零件 参数零件库 参数化图形模板的程序化虚拟 零件库 二次开发 CAD/CAPP/CAM一体化 【英文关键词】Typical Parts Parametric Parts-library Programmed Virtual Parts-library Based on Parametric Graphics Template Second Development CAD/CAPP/CAM Integration 【目录】典型零件参数化虚拟零件库及CAD/CAPP/CAM一体化系 统框架构建 摘要 3-5 Abstract 5-7 第一章 绪论 10-16 1.1 虚拟零件库概述 10-11 1.2 CAD/CAPP/CAM 一体化概述 11-13 1.3 课题研究的意义 13-14 1.4 课 题研究的主要内容 14-16 第二章 虚拟零件库及CAD/CAPP/CAM 一体化系统构建基础技术研究 16-29 2.1 虚拟零件库构建基 础技术研究 16-20 2.1.1 参数化设计技术 16-17 2.1.2 特征造型技术 17-18 2.1.3 数据库技术 18-20 2.2 CAD/CAPP/CAM 一体化关键技术研究 20-23 2.2.1 CAD/CAPP/CAM 一体化关键基础技术研究 20-21 2.2.2 CAD/CAPP/CAM 一体化系统集成方法研究 21-23 2.3 UG 二次 开发关键技术平台研究 23-28 2.3.1 基于UG 的主要功能模块 应用研究 23-24 2.3.2 UG 软件的技术特点分析 24-25 2.3.3 UG 二次开发关键技术研究 25-28 2.4 本 章小结 28-29 第三章 基于UG 的典型零件参数化虚拟零件库 的构建 29-53 3.1 参数化虚拟零件库构建思想 29-32 3.1.1 现有主流虚拟零件库构建思想 29-31 3.1.2 本文参数化图形模板-程序化虚拟零件库构建思 想 31-32 3.2 参数化虚拟零件库开发方法研究 32-35 3.2.1 现有主流零件库开发方法 32-35 3.2.2 本文参数化图形模板-程序化虚拟零件库开发方法 35 3.3 典型零件参数化图形模板-程序化虚拟零件库的构建 35-52 3.3.1 轴类零件特征分析 36-37 3.3.2 系统环境变量设置 37-38 3.3.3 用户化菜单的创建 38-39 3.3.4 轴类零件参数化模板文件创建 39-40 3.3.5 轴类零件参数 表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 达式的建立 40-41 3.3.6 用户界面设计 41-42 3.3.7 应用程序编写 42-50 3.3.8 程序化虚拟零件库的构建 50 3.3.9 虚拟零件库的运行 50-52 3.4 本章小结 52-53 第四章 基于UG 平台的CAD/CAPP/CAM 一体化系统框架构建 53-68 4.1 CAD/CAPP/CAM 一体化系统结构 53-54 4.2 系统框架功能和特性要求 54-55 4.2.1 系统框架功能 54-55 4.2.2 系统特性要求 55 4.3 CAD/CAPP/CAM 一体化系统构建关键技术 55-56 4.3.1 产品建模技术 55-56 4.3.2 工程数据库技术 56 4.3.3 数据交换的接口技术 56 4.4 系统框架构建步骤与运行实例 56-67 4.4.1 系统构建步骤 57-62 4.4.2 系统运行实例 62-67 4.5 本章小结 67-68 第五章 结论与展望 68-71 5.1 结论 68-69 5.2 后续工作与展望 69-71 参考文献 71-75 读硕士期间参加科研项目及发表科研论文情况 75-76 致谢 76-77 附录 轴类零件参数化虚拟零件库源程序部分代码 77-83
