【摘要】：经济全球化以及快速发展的信息化技术对制造业产生了极其深刻和全面的影响。如今，衡量企业市场竞争力的重要标志是企业开发和生产与众不同、满足客户个性化求的创新产品。为适应新的市场，制造企业必须转变其竞争核心、产品发展战略、技术重点、过程重点和组织重点等。制造业信息化是以信息技术为核心的高技术促进我国制造业发展的全局性、持续性和服务性的系统工程。论文结合国家自然科学基金项目（50805133），在阅读了国内外相关文献的基础上，通过对产品数据管理技术、大批量定制等技术的研究，提出了基于事物特性表的零部件主模型建模方法与相关技术。在零部件主模型的基础上，提出了基于事物特性表的零部件工艺主文档建立方法与技术，包括基于XML的主工艺文档的建立，工艺路线的建立等等，最后根据实际需求，开发了基于PDM的工艺变型系统。第一章研究课题背景和意义，分析了国内外工艺变型和CAPP研究现状，在此基础上确定了本文要研究的主要内容，并给出了论文的组织结构。第二章研究基于PDM的工艺变型设计原理及关键技术。在大批量定制理论、产品数据管理技术及工艺变型技术的基础上，提出了基于PDM的零部件建模方法及变型原理和工艺主文档的建立及变型原理，并在此基础上确立了系统总体框架。第三章详细研究支持工艺变型的零部件建模方法和工艺主文档的建立方法及变型原理。采用基于事物特性表的方法建立了零部件主模型，在事物特性表的支持下了实现零部件变型，然后详细研究了基于XML与事物特性表的零部件工艺主文档建立方法与技术，探讨了实现工艺变型机制。第四章研究UG二次开发基于事物特性表的零部件变型系统和在Teamcenter下进行开发基于PDM的工艺变型系统框架与开发技术，，详细介绍了工艺变型系统各功能模块的设计与实现。第五章根据第二章和第三章相关理论知识，结合第四章开发的变型系统，对本文研究成果进行了实例验证。第六章对全文的工作加以总结，并提出了有待于进一步研究和改进的问题。
[Abstract]:Economic globalization and the rapid development of information technology have had a profound and comprehensive impact on the manufacturing industry. Nowadays, the important symbol to measure the competitiveness of enterprises in the market is the distinctive development and production of enterprises. To adapt to the new market, manufacturing enterprises must change their competitive core, product development strategy, technical focus, Manufacturing informatization is a system engineering with information technology as the core to promote the development of manufacturing industry in China. On the basis of reading the relevant literature at home and abroad, this paper studies the technology of product data management, mass customization and so on, combined with the project of National Natural Science Foundation of China. On the basis of the main model of parts and components, this paper puts forward the method and technology of establishing the main document of parts process based on the table of things' characteristics, and puts forward the method and technology of establishing the main model of parts based on the table of things' characteristics. It includes the establishment of main process document and process route based on XML, etc. Finally, a process variant system based on PDM is developed according to the actual demand. In the first chapter, the background and significance of the research are analyzed, and the status quo of process modification and CAPP research at home and abroad are analyzed. On the basis of this, the main contents of this paper are determined, and the organization structure of the thesis is given. The second chapter studies the principle and key technology of process variant design based on PDM, based on mass customization theory, product data management technology and process variant technology. The modeling method and modification principle of parts and components based on PDM and the establishment and modification principle of main process document are put forward, and the overall frame of the system is established. In the third chapter, the modeling method of parts supporting process modification, the method of establishing main document of process and the principle of modification are studied in detail, and the main model of parts is established based on the method of tabulation of object characteristics. Based on the support of object characteristic table, this paper realizes part variant, and then studies the method and technology of establishing main document of part process based on XML and thing characteristic table in detail, and discusses the mechanism of realizing process modification. In chapter 4th, the secondary development of the part variant system based on the tabulation of the characteristics of things and the development of the frame and technology of the process variant system based on PDM under Teamcenter are studied. The design and implementation of the functional modules of the process variant system are introduced in detail. In Chapter 5th, according to the theoretical knowledge of Chapter 2 and Chapter 3, combined with the variant system developed in Chapter 4th, the research results of this paper are verified by examples. Chapter 6th summarizes the work of this paper and puts forward some problems to be further studied and improved.
