Seeking a Cpk vs z vs Pz Table
Please, anyone can give me the table for Cpk vs z vs Pz.
Appendix F of SPC manual issued by the Big3 shows z vs Pz (Probability of Defect) only.
Anyone who contribute to my request is highly appreciated.
regards,
Hisar Simanjuntak

It's not exactly clear what Hisar is trying to accomplish, but there is information Here on how to calculate what it is I think he might be looking for.
On the other hand, because z min = Cpk/3, it's a simple matter to find the z value given Cpk, and from there to find the Pz value from the table Hisar refers to in his post. Hence I'm not sure what purpose a table of equivalents would serve. If he could post back with more information it would be easier to give a definitive answer (or not).
