Process Capability Ratio PCR or Cp = ------------------------------
Skill/Topic: Statistical Process ControlA) Cp = (USL-LCL)/ 6σExplanation: In this formula, USL and LSL are the upper and lower specification limits of the quality characteristic, respectively. The quantity in the denominator, 6σ signifiesthe fact that 99.73% of the values generated by the process is contained within

The specification limits for the inside diameter of a hole are (0.995", 1.005"). The standard deviation of the inside diameters generated by a lathe machine selected to process this component is estimated to be 0.002". Compute the Cp index of this process. Assume that the inside diameters generated by the machine follow normal distribution
Skill/Topic: Statistical Process ControlA) 0.7444B) 0.8333C) 0.9673D) 0.8777Explanation: Cp = (USL-LCL)/ 6σ = 1.005 - 0.995 / (6 * 0.002 )= 0.8333
