WebCpm is a capability index, also known as the Taguchi capability index, that is a function of the specification limits, mean of the process, and a provided target, T. . The indices of Cpk and Ppk focus on centering of the mean of the distribution around the midpoint of the tolerances (USL+LSL/2) but this is not always the customer target.. Sometimes the … WebCalculate Control Limits After 20-25 Subgroups. Terms used in the various control chart formulas are summarized below: SPC Terms p = Fraction of defective units np = Number of defective units c = Number of defects u = Number of defects per unit n = Subgroup size k = Number of subgroups X = Observation value R = Range of subgroup observations WebYou can calculate Ppk for Process 1 and Process 2. Since the average and standard deviation are the same, Ppk will be the same for both processes. The calculations are: So, Ppk = 1.14 for Process 1 and Process 2. Two Processes – Same Data, Different Cpk But wait – what is the value for Cpk for these two processes? Are the same? mmhinfo mmhgroup.com
