On some processes you can do this visually. My customer wants to know if my process is capable of meeting their specifications and is in statistical control. Cpk = min(USL - μ, μ - LSL) / (3σ) where USL and LSL are the upper and lower specification limits, respectively. DPMO stands for defects per million opportunities. The Cpk formula for a one sided tolerance with a maximum (such as runout) is: (USL – Xbar)/(3 * sigma) For a one sided tolerance with a minimum is: (Xbar – LSL)/(3* sigma) where USL=Upper Spec Limit, LSL=Lower Spec Limit, and sigma is the estimated process standard deviation. It shows how closely a process is able to produce the output to its overall specifications. Max. These are the upper and lower limits of the specifications. Calculating Ppk is easier than Cpk, since Ppk is based on the overall standard deviation of the data instead of the within-subgroup standard deviation.

Good news there is an Excel add-in to do this for you. Process capability represents the performance level of the process after it has been brought into statistical control (see the January 2004 e-zine on variation and the April 2004 e-zine on interpreting control charts). You were able to see visually how the process shifts versus your specifications. The formula to calculate Cpk is given by: Cpk = Min [ (USL- Mean)/3σ, (Mean-LSL)/3σ] Where, USL = Upper Specification Limit. The worksheet will automatically calculate Cp, … The Cpk equation is: Cpk = Minimum ((Upper specification limit - Nominal value)/3 Sigma spread or (Nominal value - Lower specification limit)/3 Sigma spread)) Using the above example of water bottles, suppose the mean shifts to the right to 27 ounces. In addition, you need to calculate the standard deviation using the "STDEV" function. Cpk value <1 means bell curve will out of USL/LSL; Common Cpk vale=1,1.33,1.67 & 2; The Cpk value of a start-up manufacturing organization is supposed to be 1.33. What is the formula of Cp & Cpk?
