Xbar R Chart

Xbar R Chart - Examine the xbar chart to determine whether the process mean is in control. Examine the r chart to determine whether the process variation is in control. I showed how we can derive the xbar and r chart constants, d 2 and d 3, through simulation and used those constants to compute control limits for the xbar and range chart. Use this control chart to monitor process stability over time so that you can identify and correct instabilities in a process. They provide continuous data to determine how well a process functions and stays within acceptable levels of variation. A quality engineer at an automotive parts plant monitors the lengths of camshafts. Typically n is between 1 and 9. So, if we use x ¯ ¯ (or a given target) as an estimator of μ and r ¯ / d 2 as an estimator of σ , then the parameters of the x ¯ chart are u c l = x ¯ ¯ + 3 d 2 n r ¯ center line = x ¯ ¯ l c l = x ¯ ¯ − 3 d 2 n r ¯.
