If I'm not mistaken, FPY of a process is the ratio of the parts produced without defect "first time" to the total no of parts produced. In other words: FPY = (parts produced without defects first time / total number of parts produced)*100 "Fisrt time" refers to products without a need for repair, rework etc. If FPY is what our friend lee01 means, then it is not difficult to relate it to Cpk.
