WebProcess capability can be defined as a measurable property of a process relative to its specification. It is expressed as a process capability index C p. The process capability index is used to check the variability of the output generated by the process and to compare the variablity with the product tolerance. WebSep 11, 2024 · If you know the Upper Specification Limit (USL) and the Lower Specification Limit (LSL) of a process, then you can easily calculate the Process Capability Index using the following formula. Cpk = min [ { (USL−μ)/ 3σ} , { (μ−LSL) / 3σ)}] Where, Cpk = Process capability index. USL = Upper specification limit.
WebCapability indices: Cp. The Cp index is used to summarize a system's ability to meet two-sided specification limits (upper and lower). Like Cpk, it uses estimated sigma and, … WebMar 26, 2016 · The same capability indices that you calculate for short-term variation can also be calculated for long-term, or total, variation.
