Problem 1 (25 Points) :- Sample data collected by the operator of a lathe process is shown below. The operator took a sample of four parts at five different points in time. The operate measured the outside diameter of each sampled part and listed the results in the table below. The desired tolerance for this part is 7.250 inches 009 inches Samples 7 7.249 7.252 7.245 7.251 7.249 7.247 7.254 7245 7244 7.248 .242 7253 7245 7244 7.246 7.240 7.252 7.242 7241 7214 7.242 7.250 7.245 7245 7.240 A. Develop the Control Limits for an X-bar and R chart using this data. Place your control limits in the boxes below. UCL = X-Rar Chery R Chart B. Briefly explain how you would use these control charts on an on-going basis. (5 Pts.) C. Based on the control limits developed is the process currently in control? Explain (5 P.) D. Develop the Cp index for this process. Interpret your results
