Cpk cp

Cpk indicates shifting or closeness of process average from the target or mean value. Interpretations of Cp and Cpk. When Cp value is greater than 1 i.e. Cp value >1 : The process spread is less and all products falls within the specification limit Cp and Cpk are considered short-term potential capability measures for a process. In Six Sigma we want to describe processes quality in terms of sigma because this gives us an easy way to talk about how capable different processes are using a common mathematical framework. In other words, it allows us to compare apple processes to orange processes Cp and Cpk are commonly referred to as capability indices and we will look at the difference between Cp and Cpk. They are both used to indicate the ability of a process to make a product that meets the specified requirement

Cp and Cpk Process Capability Analysis Example

  1. Cpk: Location, Location, Location! Like Cp, Cpk is also a ratio of the specification spread to the process spread. But unlike Cp, Cpk compares the distance from the process mean to the closest specification limit, to about half the spread of the process (often, the 3-sigma spread)
  2. The Cp & Cpk calculation is based on the process mean & range and has nothing to do with how many points are in or out of spec. In actual practice, this shouldn't happen very often. The Cpk is an indicator of how centered your process is (use Cp and Cpk together to evaluate this). The Cpk calculation assumes that the data is normally distributed
  3. g. You can learn how to calculate Cp and Cpk values using this tutorial
  4. A high Cpk index means, then, that you have a good process with a small spread in relation to the tolerance width, and also that it is well centred within that width. If Cpk is equal to Cp, the process is set to produce exactly in the middle of the tolerance range (see Fig. 4). A normal requirement is that Cpk should be at least 1.33

Most people have at least heard of Cp or Cpk, but few people really understand the concepts behind the calculations Cpk is typically used while processing in the ideal conditions to identify if the process is capable of meeting the specifications. Ppk tends to be more realistic because it doesn't cut out real data, while Cpk data gathering could inadvertently skew the data into looking like a process is capable but not addressing its performance Compare Cp to a benchmark value to assess the potential capability of your process. Many industries use a benchmark value of 1.33. If Cp is lower than your benchmark, consider how to improve your process by reducing its variation. Compare Cp and Cpk. If Cp and Cpk are approximately equal, then the process is centered between the specification.
