Cpk variation
Process capability indices are constructed to express more desirable capability with increasingly higher values. Values near or below zero indicate processes operating off target ( far from T) or with high variation. Fixing values for minimum "acceptable" process capability targets is a matter of personal opinion, and what consensus exists varies by industry, facility, and the process under consideration.

Web• Ppk and Cpk are both useful measures in assessing how a particular parameter is performing vs specification. • The concept of long term common cause variation needs to be taken into account when assessing statistical control. • Understanding the nature of the underlying data is critical when interpreting Cpk or Ppk. 17 WebApr 8, 2024 · Cpk is an index (a simple number) which measures how close a process is running to its specification limits, relative to the natural variability of the process. The larger the index, the less likely it is that any item will be outside the specification.” Usually Cp & Cpk are used once a process has got steadiness or statistical control.

WebOct 23, 2008 · Cpk (and Cp) is a measure of short term process variation compared to the specification. The observed short term variation is a combination of actual process variation and measurement variation. The observed variance (s^2) is the sum of the actual variance and the measurement variance. WebIf Cpk is considerably greater than Ppk, there may be other sources of systemic variation in the process, in addition to the variation between and within the subgroups. For example, tool wear is a systemic source of variation that could cause a manufacturing process to exhibit greater between/within capability (Cpk) than overall capability (Ppk).
