Forgot how to calculate.
I am looking at some information that was given to me.
Exact thickness 125.00
usl+2.00
lsl -2.00
mean 124.99
cpk 1.883
sigma .352
Zusl: 5.721
Zlsl: -5.648
Zmin: 5.648
I haven't been able to come up with where they got th Z vaues from.
I haven't done these calculations for a long time. Can anyone help.
