Cp = (USL C LSL) / (6 x sigma); Var: USL = övre specifikationsgränsen. LSL = lägre specifikationsgränsen. Nackdelarna med Cp åtgärdas av Cpk. Båda är Sida: 1 (5). 1.1 Inledning.

但是计算cpk，通常都是考虑有1.5倍sigma的偏移，所以实际的会小一点。三个变量的CPK和总体合格率之间本来就没有特定的公式关系，总体合格率和总体CPK有关系，单个CPK和单项的合格率有关系。 Cp与 Cpk 二者着重点不同。联合使用才对。一般考虑过程有+-1.5 sigma 的偏移。 4sigma ，6210ppm 5sigma 233ppm 6sigma 3.4ppm Cpk=1.33 Cp=1.33 时，合格率99.994% 与5sigma基本相当 Cpk=1.33 Cp≥1.67 时，合格率99.9968% 与5.5 sigma基本相当 Cpk=1.67 Cp=1.67 时，合格率99.99994% 已经6 sigma水平了。 3.Ideal value for a Cpk should be either at 1.33 or 1.66(close to 4 or 5 sigma) since there can be space for a process drift either to the left or right of the nominal value (target value). 4.

I rapporten beskrivs ett förbättringsarbete utifrån ett sex sigma perspektiv, där 5. 1.1 Bakgrund till problemet . 2.2.5 Control (Reglera, bevaka, kontrollera).

The Six Sigma scale tolerates drift in process whereas Cpk clamps a penalty on drift (Cpk=Cp(1-k) where k is the penalty number), in a loud and clear manner. Accepting drift has misled us and left Does .NET 4 support any 6-Sigma calculation?
