WebDec 26, 2024 · Here the formula of Cpk i. e. (Process Capability Index) is represented by, Cpk = min [ (USL−mean)/3σ, (mean−LSL)/3σ] There is a slight difference between Cp and Cpk. The difference between Cpk and Cp is given here. The Cp is used to measure the ability of the process to meet the specification of the particular product. 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.
