【摘要】 “质量新时代”的到来对企业质量管理提出了更高的要求，新兴的六西格玛质量管理是企业进行质量控制和管理强有力的方法工具。本文以“面向加工过程的六西格玛质量管理系统开发及其应用研究”为题进行了研究，在分析国内外对六西格玛研究和应用的基础上，探讨了微型轴承加工过程的工序质量控制和管理方法，开发了面向加工过程的六西格玛质量管理的原型系统，并进行了实例应用研究。全文共分六章：第一章，阐述了质量管理的发展和目前六西格玛质量管理的研究概况，并结合我国微型轴承加工的质量现状，重点介绍了六西格玛质量管理在加工过程中的应用前景，从而引出本文的研究课题——面向加工过程的六西格玛质量管理系统开发及其应用研究。第二章，首先简述了构建本系统的理论基础——六西格玛质量管理理论，然后通过对工序质量控制的分析，得出面向加工过程的六西格玛质量信息系统的功能需求，最后在此基础上阐述了本系统的体系结构及其重要模块。第三章，六西格玛质量管理是以数据和事实为基础的，因此质量检测和数据采集模块是系统的一个重要部分，本章介绍了应用于微型轴承套圈质量检测和数据收集的单片机电感测微仪的设计开发，并将信息技术与六西格玛统计指标、管理模式结合起来，对系统的测量模块进行测量系统分析。第四章，在前两章研究结果的基础上，建立了面向加工过程的六西格玛质量管理信息系统的数据库结构和主要的数据字典，给出了系统的模块结构图，阐述了各模块的功能和信息交互方式，以及分析模块的逻辑结构，并对异构数据库数据迁移的方法进行研究，从而实现了单片机电感测微仪自动采集数据与系统数据库的集成。最后，在此基础上开发了一个计算机辅助的面向加工过程的六西格玛质量系统管理的原型系统，并结合实例介绍了该系统的开发工作和系统的运行情况。第五章，结合本系统在微型轴承套圈磨削加工中的具体应用，研究系统在质量目标的制订、质量检测与数据收集、质量分析、质量改进以及质量控制等方面所发挥的作用。系统为DMAIC循环模式方法在制造企业中的运作，提供了方便有效的方法工具，有助于制造企业应用六西格玛方法对加工过程进行质量管理和质量控制。第六章，主要是对本论文作一个总结，并对以后的研究作了一个展望。更多还原

【Abstract】 The arrival of "new era of quality" asks for higher requirements to enterprise quality management. It is no doubt that Six Sigma quality management is the powerful instrument for enterprise to control quality. Based on home and abroad research and application, this article focuses on "Study and application on Six Sigma quality management system for manufacturing process", discusses the methods of process capability quality control and management in miniature bearing manufacturing conditions. Furthermore, we develop Six Sigma prototype system for manufacturing process and research it with real practice.The whole thesis is divided into six chapters:Chapter one illustrates the development of quality management and the general research situation of Six Sigma initiative at present. Six Sigma is upcoming quality improvement process and is proving to be a powerful tool for solving complex problems, especially in manufacturing issues. Later we introduce our research topic- Study on Six Sigma Quality Management System for Manufacturing Process.Since quality control during manufacture process plays an important role in product quality of miniature bearing, in Chapter two, we derive the function requirement of the system by analyzing to quality control activity of miniature bearing manufacture process and using the Six Sigma principle and method. Based on above idea, we construct the structure of the system , and give the function module of it.Data collection is the significant module of the system. In Chapter three, we introduce the development of inductance micro-meter dial with single chip micro-computer, which can inspect and collect quality data of miniature bearing ferrule accurately in good time, we also execute measurement system analysis for measuring module with Six Sigma statistic index and methods.According to above system requirement analysis, in Chapter four, we construct the database structure and date dictionary of primary objects, give the program structural module, illustrate the function of each module and the communication ways of each other, and finally we develop the prototype system of the Six Sigma quality management system for manufacturing process.In chapter five, we research the application analysis of the system with example in miniature bearing manufacturing process. Based on the system, the experience of applying the Six Sigma approach and its data analysis tools to the resolution of manufacturing issues has yielded significant results.Finally, chapter six makes a conclusion of the whole thesis and puts forward the future research in this field.更多还原
