The thickness of composite panels is an important quality characteristic. The specifications for the thickness are 4.00±0.01 mm. If a process capability ratio Cp of at least 2.0 were desired for the centered process, what would be the LCL for the R charts to use with a subgroup size of six? A. 0.001 B. 0.0011 C. 0 D. 0.0001

Step 1
The specification limits are given as 4.00 ± 0.01 mm, which means the upper specification limit (USL) is 4.01 mm and the lower specification limit (LSL) is 3.99 mm. Show more…

The proportions of nonconforming switches in 20 subgroups of size 100 are shown in the following chart: a) If the central line of the chart is 0.0585, calculate the control limits, and briefly comment the process, including all the potential special causes. b) Please explain why LCL is negative and how to handle it? c) For a fixed subgroup size n, what values of the central line will lead to a positive lower control limit on the chart?

The data below are X and R values for 12 samples (subgroups) of size n=4. They were taken from a process producing bearings. The measurements are made on the inside diameter of the bearing. (Use 2 decimal places.) A - Calculate the UCL and LCL for X and R charts. B - Draw the X chart and R chart and place X and R values (points) on these charts. C - Does the process seem to be in control? Why or why not? D - If necessary, revise the control limits. Calculate the revised UCL and LCL values for X and R charts and draw the revised charts.
