The data shown in Table 1 are the deviations from nominal diameter for holes drilled in a carbon fiber composite material used in aerospace 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? (6) Estimate the process standard deviation using the range method. C) If specifications are at nominal +100, what can you say about the capability of this process? Calculate the PCR Cp.
