9- A process is in statistical control with x= 39.7 and R=2.5. The control chart uses a sample size of n= 2. Specifications are at 40 5. The quality characteristic is normally distributed. n=2; ร€=ลพ= 39.7; R=2.5; =R/d, = 2.5/1.128=2.216 USL = 40 + 5 = 45; LSL = 40 – 5 = 35 (a) Estimate the potential capability of the process. (b) Estimate the actual process capability. (c) Calculate and compare the PCRs Cpm and Cpkm.
