I am having difficulty understanding why my CpK and PpK are under the acceptable value. Our process is very stable, and SPecs are 65.8+-0.4 for the results below. Does my process need to be more out of control in order to properly calculate or identify CpK? I had the same issue last week determine gauge R&R because our process was so stable.
Thanks!
