Gauge capability index

WebMost research works related to process capability indices assume no gauge measurement errors. However, such an assumption inadequately reflects real situations even when advanced measuring instruments are employed. If we do not take into account these errors, conclusions drawn from process capability are therefore unreliable. WebCapability indices are calculated only when the gage tolerance is specified. The capability of the gage, considering both the gage variation and the bias, is calculated by: Notation. Term Description; K: the percent of the tolerance for calculating C g specified in the …

WebFeb 26, 2010 · The difference between capability rates ( Cp and Cpk) and performance rates ( Pp and Ppk) is the method of estimating the statistical population standard deviation. The difference between the centralized rates ( Cp and Pp) and unilateral rates ( Cpk and Ppk) is the impact of the mean decentralization over process performance estimates.
