Let's take a closer look at each and find out. WebbCp and Pp are a ratio of the entire specification range for a given characteristic to its entire process range, whereas Cpk and Ppk are a ratio of the distance between the process mean and closest specification limit to half the process range. Let return to our lathe example: Average = 12.140 mm. Standard deviation = .110 mm.

Webb12 dec. 2016 · The one-sided defect rate is applicable to any capable process with 1-sided or 2-sided SLs, even at a 3-sigma level. Given the specification limit, SL, the process sigma level, or process Z, is: Z = (x – μ) / σ = (SL – μ) / σ. In this example, the process sigma level for a specification limit of 31 seconds is: Z = (SL – μ) / σ.
