WebProcess capability analysis with the Cp ratio shows how well the process spread (expressed as six standard deviations) fits into the specification range. This measurement is determined by dividing the specification limit … WebThe process capability index is defined as the quotient between the length of the acceptance interval and six times the standard deviation obtained as a result of the design and production processes (Taguchi, Elsayed and Hsiang, 1989 ). The response should be made dimensionless by using the variables defined in (3.13).
