Web6.4. Calculate Cpu and Cpl. Cpu and Cpl are the Cpk values calculated for both Z values. From Cpu and Cpl, it is evident that the smaller value for the example is Cpu, which is the same value as Cpk. By comparing Cpu to Cpl, it is evident that the overall average is off center and closer to the upper specification than the lower specification. WebNo, the current process is not "Six Sigma" good because the process capability indices Cp and Cpk are both less than 1. A Cp of 0.79 indicates that the process has a high level of variability relative to the specification limits, and a Cpk of 0.12 indicates that the process is not centered between the specification limits.

WebA Cpk index of 1-O for both the upper and lower specification limits indicates that the process variation is within the upper and lower 30 specification limits and Cpk will be the same when the process is centered. Operating characteristic curve (oc) - a graph that describes how well an acceptance plan discriminates between good and bad lots. The process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control. This means it cannot account for deviations which are not expected, such as misaligned, damaged, or worn equipment. Process capability indices measure how much "natural variation" a …
