5-3. The data shown here are the deviations from nominal diameter for holes drilled in a carbon-fiber composite material used in acrospace manufacturing. The values reported are deviations from nominal in ten-thousandths of an inch. (a) Set up x and R charts on the process. Is the process in statistical control? (b) Estimate the process standard deviation using the range method. (c) If specifications are at nominal \pm 100 , what can you say about the capability of this process? Calculate the PCR Cp. 5-3.
