Good evening everyone, I'm new to stats/process control but I'm trying to gain a better understanding so I can improve some of the processes I'm responsible for.
I have two sets of data, 20 samples of a 'good' part and 20 samples of a 'bad' part. I want control limits that will give me a Cpk of 1.33. Currently I'm adjusting my control limits in to Minitab, generating charts, observing the Cpk, then readjusting limits until I achieve the desired index.
Is there a way in Minitab to enter my sample values, desired Cpk, and have MiniTab generate the limits for me? Seems like I'm working backwards at the moment, thanks for your help.
