process capability excel template 20150102.png. Process Capability is the total range of inherent variation in a stable process. A process capability study uses data from an initial run of parts to predict whether a manufacturing process can repeatably produce parts that meet specifications. QI Macros calculations are tested and accurate. Cp and Cpk should be close in value to Pp and Ppk. For a detailed mathematical account of capability indices, we … Generally, the final solution of the process capability is specified either in the form of calculations or histograms. To learn more about capability analysis and related topics, refer to the following articles and discussions on iSixSigma.com: C p, C pk, P p and P pk: Know How and When to Use Them; Capability and Performance QI Macros contains advanced features like one-sided spec limits. How centered the data is between the spec limits. The concept of process capability only holds meaning for processes that are in a state of statistical control. Process Capability Analysis for Normal Distributions CP and PPM interpretation Process Spread LSL USL Specifications Case 1: CP > 1.33 A fairly capable process This process should produce less than 64 non-conforming PPM.

Process Capability Analysis In this chapter we give the mathematical background of process capability analysis, in particular the capability indices Cp and Cpk and related topics like tolerance intervals and density estimation. When the data is not normally distributed, capability analysis can still produce useful results by using nonparametric indices, or by transforming the data so that it conforms better to normal distribution than its original form. Think of these specification limits as goal posts. The output of this measurement is usually illustrated by a chronological control sample, histogram and calculations that predict how many parts will be produced out of specification (OOS). If Cp = Cpk the process is centered at the midpoint of the specification limits. (Cpk or Cp) or as a process performance index (e.g. KnowWare International, Inc.
