Process Fit (Cp and Cpk) Problems: 7. A certain process has an upper specification limit of 320 and a lower specification limit of 280. The process standard deviation is 6 and the mean is 290. a. Calculate Cp and Cpk for this process. b. What could be done to increase the process capability Cpk to 1.0? 8. A certain process is under statistical control and has a mean value of u = 100 and a standard deviation of o = 10. The specifications for this process are USL = 120 and LSL = 70. a. Calculate Cp and Cpk. b. Which one of these indices is a better measure of process capability? Why? c. Assuming a normal distribution, what percent of the product can be expected to fall outside the specifications? 9. A customer has specified that they require a process capability of Cp = 1.5 for a certain product. Assume that the USL = 1100 and LSL = 900, and the process is centered within the spec range. a. What standard deviation should the process have? b. What is the process mean value? c. What can the company do if it is not capable of meeting these requirements
