摘要
介绍利用x-R控制图对工件生产过程进行质量控制,并用Minitab14作为开发工具对质量数据进行统计处理,通过所得的质量控制图分析产品的质量变化。
The method to use ^-x- R chart to control work-piece' quality was introduced, and Minitab 14 was applied as a tool to process quality data, then the changes of quality of production was analyzed through quality control chart drawn by Minitab 14.
