加工质量的初始研究和在线控制

EARLY RESEARCH AND ONLINE CONTROL OF PROCESS QUALITY

针对加工过程的输出特性定期抽检若干组数据,利用VisualC++对数据进行处理,绘制出均值-极差控制图,通过分析控制图,可以实时监测加工质量随时间的变化情况。

For an identity of processes, we collect some groups of data at interval. With Visual C ++, we process these groups of data, draw the control chart of biggest margin and even. Analyzing the control chart, we can watch the changes of qualities of the process in different time.
