WebInference: From the above Capability report, we can conclude that the process is capable of meeting the specification limit, but the process is skewed towards left due to non-centering of mean. The Cpk less than 1.00 indicates the short term capability is bad. As the short term itself is bad, there is no need to check the overall capability i.e ... http://www.differencebetween.net/miscellaneous/difference-between-cp-and-cpk/
Cpk Vs. ppm - Relating Process Capability to Defect Rate
WebFor instance, if your Cpk is 1.33 (Cpk > 1.33 is desirable), and you increase your sample size, your UCI will lower, while your LCI will rise, which creates a smaller window of Confidence – this is good, as it shows a minimizing … WebPp is a measure of the overall capability of the process. Pp is a ratio that compares two values: The specification spread (USL – LSL) The spread of the process (the 6-σ variation) based on the overall standard deviation. Pp evaluates overall capability based on the variation in the process, but not on its location. rwby ruby wolf faunus
