Hello all,
I have a question. We are in technical review prior the offer, our customer is requesting a min Cp/Cpk of 2 on some characteristics.
Just as pure example, assuming that the dimension is 40 +/-0,3, that the Cp/Cpk in serial production has to be >2, how can I calculate in advance which should be UCL/LCL I have to keep in serial life or how should much I should close the tollerance range during setting my process in order to achieve the Cp/Cpk?
Many thanks for your help!!!
