I have an problem with a couple of people understanding if a Cpk value can be determined off of the following specifications:
Spec for hole: .165 +.000/-.004.
One person is telling me no Cpk value can be determined b/c there is no nominal spec and that this is a 1-sided specification limit.
My statistical engineer states that for Cpk analysis there is no nominal needed and the USL is .165 and the LSL is .161.
I tend to agree with the stats engineer.
Please point me in the right direction of a article or book that will state one or the other view point correctly. I need to clearly give a direction so that the arguement may end.
Thanks for your help.
