What is the formula for CP and CPK in Excel?
What is the formula of Cp & Cpk? Cp= ((USL-LSL)/ (6 x Standard Deviation)) , where USL=Upper Specification Limit & LSL=Lower Specification Limit.
What is Cpk process capability?
Cpk is the “Capability Index”. It is a measure of the capability of a process to provide output that is within the process specification limits. The Cpk formula, applies an estimate of sigma, which details the potential of a process to meet specifications. The Cpk formula, includes reference to the process mean.
What is the formula to calculate Cpk?
The formula for the calculation of Cpk is Cpk = min(USL – μ, μ – LSL) / (3σ) where USL and LSL are the upper and lower specification limits, respectively. A process with a Cpk of 2.0 is considered excellent, while one with a Cpk of 1.33 is considered adequate.

What is the Cpk value for Process centering?
In this case, Cpk uses CpkU which means Cpk > 1. Cpk < 1 because the mean is closer to zero. Cp > 1 Process is capable (product will fit between the customer’s upper and lower specification limits if the process is centered). Cpk > 1 Process is capable and centered between the LSL and USL.
