If the cpk index exceeds 1:

WebThe larger the Cpk value the closer the mean of the data is to the target value. Cpk is calculated using the specification limits, standard deviation or sigma, and the mean value. The Cpk value should be between 1 and 3. … WebAls geldt Cpk > 1,0 betekent dat het proces met grote zekerheid voldoet aan de specificaties. Wanneer Cpk gelijk is aan 2 is sprake van een proces op 6 sigmaniveau (3,4 DPMO). Een hoge Cp-waarde is een noodzakelijke, maar niet afdoende conditie voor een goede sigmawaarde voor een proces. Een hoge sigmawaarde is alleen mogelijk …

Web11 okt. 2024 · The Cpk index of 1.81 represents a sigma level of approximately 5.5, which is still considered world-class. Under perfect conditions, a process with a mean aligned with its target value will yield ... WebA: Shift the mean to center the process between the specs, without increasing the variation. Example 2: The analysis for Diameter 2 shows that Cp = 0.43 and Cpk = 0.41. Because Cp is bad, we know there’s too much variation—our car cannot physically fit in the garage. And because the Cp and Cpk values are similar, this tells us that the ... indirect index match関数
