The metal exterior of a smartphone is stamped out of aluminum sheets. The part has to be 15 cm in size (D). The acceptable tolerance set by the engineering team is ±0.05 cm (USL and LSL). The average size of the current stamping process is 14.97 cm (m) with a standard deviation of 0.02 cm (s).

Calculate C_p and C_pk. .Is the process capable of producing 6s quality? What can or should be done? If the process engineering team adjusted their tolerance to ±0.05 cm and manufacturing can improve the standard deviation (s) to 0.008, what is the new C_p and C_pk? Is the revised process capable of producing 6s quality?
