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.

It is the ability of the combination of your 5 M's to produce a product that Explanation: A process with Cpk of 2.0 (+/- 6 sigma capability), i.e., the process mean. Six Sigma includes five steps: D.M.A.I.C -- define, measure,analyze,improve & control. ". Process capability index (cpk) is the measure of process capability. When Cpk is greater than 1, the process is in better shape to perform at acceptable levels. As a rule of thumb, a minimum Cp and Cpk value of. 1.33 (4 sigma) is  Cpk: the one-sided capability index, calculated from.

Definitions for Six Sigma • Six Sigma is a way to measure the chance that a unit of product or a work process can be manufactured or performed with virtually zero defects. • For variables, Six Sigma is Cp ≥ 2 AND Cpk ≥ 1.5 • For attributes, Six Sigma is no more than 3.4 defects per million. 2006-06-10 · A Cpk exactly equal to 1.0 would imply that the process variation exactly meets 3 Sigma. A Cpk exactly equal to 1.33 would imply that the process variation exactly meets 4 Sigma. If the process shifted slightly, and the out of control condition was not immediately, if not sooner, detected, then the process would produce scrap. sigma水平、公差范围、CPK与不良率(PPM)对照表 - σ 水平、公差T、CPk水平与不良品率的关系一览表 %T 1666.7% 769.2% 625.0% 454.5% 357.1% 3 People often ask for a Cpk index, as assurance that items being produced will be satisfactory.
