Question

3) If a process has a Cpk of 1.33, How many Standard Deviations would that cover? If the process produced 100,000 parts, how many non-conforming parts would you expect to produce? Would you feel the need to 100% Inspect?

Answer 1

We need to do sample inspection only if Cpk value is 1.33. There is no need to do 100% inspection unless the customer asks for it.

Ce e: whether measures the parts 24 produced 1 by process CPK: gut measures how closely a process compared produce the components to its can Specification limits 26 a process has Cervalue of at leart 1.33, it would cover 4 Standard deviations (46) dret → dn 4 6 produced in every minion components there will be errons in 6200 Components. P er million gives – 6200 error 100.000 parts give → 5200 x 105 106 = 620 par
