In process improvement efforts, the process capability index or process capability ratio is a statistical measure of process capability: the ability of a process to produce output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control. Process capability indices measure how much "natural variation" a process experiences relative to its specification limits and allows different processes to be

You can learn how to calculate Cp and Cpk values using this tutorial. Mittlerweile wird vielfach ein C p-Wert von 2,00 (die Breite des Toleranzbereichs entspricht einer Streubreite von ±6 Standardabweichungen, daher Six Sigma) kombiniert mit einem C pK-Wert von 1,67 (der Abstand der nächstgelegenen Toleranzgrenze vom Prozessmittelwert beträgt mindestens 5 Standardabweichungen) als wünschenswertes Ziel definiert. • A Cp of 0.5 means that the specification limits are half the width of the total predicted process variation. • A Cpk of 0.5 means that half of a Normal curve will fit between the average and either performance limit, so this process is at a 1.5 sigma level. Six Sigma Conversion Tables: Two tables below provide both short-term and long-term conversions of Sigma Level (Z-Score), CPK or PPK, and Defect Rate respectively. Notice the difference between short-term and long-term is an industry standard 1.5 shift of the Sigma Level. Short-Term Cpk is a standard index to estimate the capability of one process, the higher the Cpk value the better the process is.

La capabilité est une méthode de mesure de l'aptitude d'une machine, d'un procédé ou d'un moyen de mesure. MSP et SPC, Calcul du CP et CPK - statistiques.

And, we've So with USL at .5 and LSL at 0, Cpk is calculated as follows:. The Cpk calculation uses the half value of [USL-LSL] when the process is centered, otherwise it is derived from the distance between µ and the closest. The following table lists Defects Per Million Opportunities with the corresponding Sigma Level. Also shown is a direct conversion to a Cpk level based on the Cp Cpk. 1.0.

If Cpk is in the vicinity of 0 and 1.0, not all procedure yield meets specifications. If the framework is fixated on its objective value, Cpk ought to be utilized as a part of conjunction with the Cp index. Cpk and Cp will be equivalent when the procedure is fixated on its objective esteem.

6 Assuming a two-sided specification, if \mu and \sigma are the mean and standard deviation, respectively, of the normal data and \mbox{USL}, \mbox{LSL}, and T Ju större Cm-tal, desto bättre maskin. Exempel: Om Cm är 2,5 får maskinens spridning plats två och en halv gång inom toleransvidden, medan Cm 1,0 betyder att Enligt Motorolas "sex sigma" program gäller Cp>=2 och Cpk>=1,5.

If we look at the formulas for Cpk and Ppk for normal (distribution) process capability, we can see they are nearly identical: The only difference lies in the denominator for the Upper and Lower statistics: Cpk is calculated using the WITHIN standard deviation, while Ppk uses the OVERALL standard deviation.

För er som trodde 5W hade med 5 varför analyser att göra så kommer det lite förekommer i 6 sigma processerna, men som vi även använder vid behov. Histogram - lämpliga vid t.ex. toleransproblem, tekniska avvikelser, Cp och Cpk.

Cpk is the centering capability index. It measures how well the data is centered between the spec limits. Use Cp Cpk when you have a sample, not the population, and are testing the potential capability of a process to meet customer needs. Cp and Cpk use Sigma estimator.
