Cpk reliability

WebCpk is calculated using the specification limits, standard deviation or sigma, and the mean value. The Cpk value should be between 1 and 3. If the value is lower than 1 the process is in need of improvement. ... Quality-One … WebLike the more popular indices, Cmk also has a corollary, Cm, that does not account for centeredness. As you might expect, its formula is identical to Cp and Pp: Cm = (U SL−LSL) 6σ C m = ( U S L − L S L) 6 σ. Interpreting Cm and Cmk is also identical in that: 1) Higher is better, and 2) a 1.0 means that the process exactly covers the full ...
