Abstract：Traditional Shewhart control charts have low power in detecting mean shift of quality characteristics under control. When an individual-moving range control chart(X-Rm) is used to control its deviations of fluorine filling amount, It is found that X-Rm is too insensitive to the shift of the deviations and unable to calibrate its fluorine filling machines in time. A CUSUM control chart is used to solve the problem and to improve machine calibration, which results in high quality and low cost in fluorine filling process.
