摘要:  为了解决某公司常闭阀罩生产过程中质量不稳定、生产过程能力低等问题,将质量管理方法应用于常闭阀罩生产的管理过程。利用测量系统分析、过程能力分析、一元线性回归分析等方法进行产品质量的分析,并结合Minitab 软件里面的功能模块,精确计算过程能力指数,生成控制图,根据判定准则,给出判定结论。企业应用实例表明,该公司在实施了质量控制后,过程能力提高,废品率降低,有效地提高了产品质量。

Abstract: Observing the quality problems in a closed valve cover enterprise, quality control theory and methods are used to improve the quality of closed valve cover. First, a praetor diagram method is used to analyze the product quality problems;and then, using measurement system analysis, process capability analysis is made to find the key factors;using a fishbone diagram, a linear regression analysis is made to design the improvement scheme;using Minitab software, data is analyzed. Finally, improved improved improvedtithe project is successfully implemented, whose result shows that failure rate is reduced largely, and the process capability improved from 0.54 to 1.22.

Key words: quality control, measurement system analysis, process capability, fishbone diagram
