【摘要】：机械零件质量追溯与评价的目的在于提高零件质量,同时在促使企业发展和提高客户满意度上也起着重要的作用。机械零件生产过程参与的因素众多,原材料种类繁多、人员、设备、工艺、加工环境等因素对零件质量的影响急剧增加,质量问题频频发生。面对突发的质量问题,企业往往采用"事后反馈"来处理。本文在"事后反馈"的基础上,融入"事中控制",形成质量追溯与评价系统,通过"事中控制"减少"事后反馈"的频率,在零件加工过程中消除零件异常,进而提高在制品的质量,整体上提高零件的质量。本文以陕西北方动力有限公司曲轴事业部为研究背景,以机械零件为研究对象,研究了质量的可追溯信息,并采用控制图评价零件质量。首先,对影响零件质量的因素进行分析,针对国内外研究和零件的特点,从零件的形成过程出发,研究了影响零件质量的四个阶段:设计、原材料采购、加工和销售,确定出质量追溯信息。然后,分析了控制图的原理和评价流程,采用质量控制图来评价零件质量。利用控制图的判异准则评价零件加工过程的质量关键点的异常。最后,通过系统开发实现质量追溯与评价。本系统采用java语言进行编程,后台程序采用SSH架构,前端页面通过jsp、css、js等技术实现,所采用的开发工具是myeclipse、tomcat及mysql数据库。开发流程包括:需求分析、模型处理(建模)、功能设计、页面设计、程序设计。
[Abstract]:The purpose of tracing and evaluating the quality of mechanical parts is to improve the quality of parts, at the same time, it plays an important role in promoting the development of enterprises and improving customer satisfaction. There are many factors involved in the production process of mechanical parts. Many kinds of raw materials, personnel, equipment, technology, processing environment and other factors on the quality of parts increased sharply, quality problems occurred frequently. In the face of sudden quality problems. Enterprises often adopt "feedback after the event" to deal with it. Based on the "feedback after the event", this paper integrates "control in the incident" to form a quality traceability and evaluation system. Through "control in the incident" to reduce the frequency of "feedback after the event", eliminate the abnormal parts in the process of parts processing, and then improve the quality of the products in process. This paper takes the crankshaft business department of Shaanxi North Power Co. Ltd as the research background and takes the mechanical parts as the research object to study the traceability information of the quality. The control chart is used to evaluate the quality of parts. Firstly, the factors affecting the quality of parts are analyzed, and according to the characteristics of the parts at home and abroad, starting from the forming process of the parts. This paper studies the four stages that affect the quality of parts: design, raw material purchase, processing and sales, and determines the quality traceability information. Then, the principle and evaluation flow of the control chart are analyzed. The quality control chart is used to evaluate the quality of the parts, and the difference criterion of the control chart is used to evaluate the anomalies of the key points of the quality of the parts in the machining process. Finally. Through the system development to achieve quality traceability and evaluation. This system uses java language to program, the background program uses SSH structure, the front page is realized by jspsphcssjs and other technologies. The development tools used are myeclipsetomcat and mysql database. The development process includes: requirement analysis, model processing (modeling, function design, page design). Programming.
