WebAug 11, 2014 · But, we have another problem. CpK is a measure of the distance to the nearest tolerance limit divided by 1/2 the process spread (which would be 3 x 1.67 = 5.0 or 1/2 the spread of 10). Since the … WebThe addition of “k” in Cpk quantifies the amount of which a distribution is centered. A perfectly cantered process where the mean is the same as the midpoint will have a “k” value of 0. The minimum value of “k” is 0.0 and the maximum is 1.0. A proper centered process will have Cp = Cpk. An estimate for Cpk = Cp (1-k). generated token\\u0027s initial ttl
