Components used in a digital SLR camera are manufactured with nominal dimension of 0.3 mm and lower and upper specification limits of 0.295 mm and 0.305 mm respectively. The x- and R control charts for this process are based on subgroups of size 5 and they exhibit statistical control, with the center line on the x- chart at 0.3020 mm and the center line on the R chart at 0.00144 mm. Estimate the mean and standard deviation of this process. Suppose that parts below the lower specification limits can be reworked, but parts above the upper specification limit must be scrapped. Estimate the proportion of scrap and rework produced by this process. Suppose that the mean of this process can be reset by fairly simple adjustments. What value of the process mean would you recommend? Estimate the proportion of scrap and rework produced by the process at this new mean.
