However, this is not realistic and with this case, I I can not control the upper limit used historical values (within stdev and mean); still Ppk below 1. Your measurements must follow the rules below: Gage Resolution: Gages should be calibrated and gage resolution should be at least 1/10th the specification. If, however, the Process Spread is greater than the Engineering tolerance, then the process variation will not fit within the tolerance and the process will not be capable (even if the process is centered appropriately).

The larger Cpk is, the less likely it is that any item will be outside the specification limits. And because the Cp and Cpk values are similar, this tells us that the . Thanks for the question! 228 Direct 404-879-5528 Fax 404-872-1477 james.berto@sreb.org http://www.sreb.org. Is this related to SPC? In the Cpk equations, is used to estimate the process variation.
