WebA Cpk of 1.10 is more realistic than .005 for the data given in this example and is representative of the process. As this example illustrates, setting the lower specification equal to 0 results in a lower Cpk. In fact, as the process improves (moisture content decreases) the Cpk will decrease. When the process improves, Cpk should increase. WebMar 6, 2024 · Cpk is a process capability index that determines how much a process can produce. Cpk, unlike Cp, does not assume the process mean is centered between the …
WebApr 9, 2024 · Interpretations of Cp and Cpk. When the Cp value is greater than 1 i.e. Cp value >1: The process spread is less and all products fall within the specification limit.Here the process is said to be quite capable of meeting the specification limit..

See more WebThe relative increase in ΔI 1,1 /I 1,0 was indistinguishable in the presence (+CP/CPK) and absence (−CP/CPK) of creatine phosphate (CP) and creatine phosphokinase (CPK) as [ADP] increased. There was a subtle increase in inter-filament lattice spacing with increasing [ADP] in the presence and absence of CP and CPK ( Figure 2 B).
