When quality control is aimed at monitoring whether or not the produced out of the specification, not monitoring the process, then using acceptance control chart is more desirable. Nevertheless, when the process mean shifts quickly that is related to tool wear, it may reduce the sensitivity of acceptance control chart by using a fixed sampling interval. In this study, we use variable sampling interval to build a Variable Sampling Interval - Adaptive Acceptance Control Chart based on adaptive acceptance control chart. We improved the sensitively of the adaptive acceptance control chart by using variable sampling interval.
