WebDec 21, 2024 · The most commonly used capability indices are CP and CpK. CP, which stands for capability of process, is the ratio of tolerance to 6 Sigma. The formula is: he 6σ in the CP formula comes from the fact that, in a normal distribution, 99.73% of the parts will be within a 6σ (±3σ) spread when only random variation is occurring. WebThe processing capability or the Cp formula is measured with the help of an upper specification limit, a lower specification limit, and the standard deviation. After it is calculated, sufficient data must be taken from the result in order to make a conclusion. A perfect process capability is one that has a value of 1. hockeyshot extreme triangle passer 2.0
