Problem 28 An automatic lathe produces rollers for roller bearings, and the process is monitored by statistical process control charts. The central line of the chart for the sample means is control as established by samples of size 5. The upper and lower specifications for the diameter of the rolers are (8.80 +0.25) and (8.80 0.25) mm, respectively, Click the icon to view the table of factors for calculating three-sigma limits for the x-chart and R-chart. a. Calculate the control limits for the mean and range charts. The UCLp equals Immand the LOlp equals mm. (Enter your responses rounded to two decimal places.)
