I see what i did wrong, I should have put in more 3’s into the CP value
1.333*6 = 7.99998
10.3/7.99998 = 1.2875
which is the correct answer 2 months, 3 weeks ago
I was able to get that far. I wouldn’t even have to find USL because the specification width was given. Still, for the sake of learning I will fill this out and re-engineer this here to the best of my ability. I have the correct answer so I know i’m wrong anyways.
(340.3-330)/6SD = CP
10.3/6SD = CP
10.3/SD = 6CP
SD = 61.8CP
And I do not…[Read more]
Can someone walk me through this problem?
1) The lower specification limit (tolerance) for a particular output is 330mm
2) The specification width for this output is 10.3mm
3) This output’s process mean is “centered” within the specification interval
If our goal is a process that has a Cp that is at least 1.333,
what is the…[Read more]
