Suppose that the design engineering team set the specifications for length of a stamped sheet$-$metal part at $10$ inches $($D$)$ with acceptable tolerances of $\backslash$pm $\mathrm{.}05$ inches $($USL and LSL$).$ The average length of the products produced by the actual stamping process is $9\mathrm{.}99$ inches $()$ with a standard deviation of $\mathrm{.}015$ inches $().$ The calculations for the Cp and Cpk are as follows:
