Cpk processing
WebPotential capability (Cp) and actual capability during production (Cpk) are process capability estimates. C p and C pk show how capable a process is of meeting its specification limits, used with continuous data. They are valuable tools for evaluating initial and ongoing capability of parts and processes. WebA Cpk analysis shows the histogram of the process output with a normal curve and the specification limits added to the chart. In this example, you can easily see that the process output is within the specification limits. …

WebCp and CpK are statistical measures used to assess a process’s capability. They are calculated using data from samples that are taken from the process. The Cp measure is calculated as follows: Cp = (Upper Specification Limit – Lower Specification Limit) / (6 * … WebA Cpk of 2.00 implies that the process uses only 50% of the spec width, significantly reducing the risk of defect. A high Cpk value has two important benefits: (1) You'll be producing fewer defective parts (2) You'll improve …
