A certain process measurement has a mean of 49 and a standard deviation of 1. The specifications call for 50 ± 5. What is the value of the process capability index (Cpk)?
Homework Answers
Cpk = MIN(UPPER LIMIT - MEAN / 3 * STANDARD DEVIATION, MEAN - LOWER LIMIT / 3 * STANDARD DEVIATION)
UPPER SPECIFICATION = 55
LOWER SPECIFICATION = 45
MEAN = 49
STANDARD DEVIATION = 1
Cpk = MIN(55 - 49 / 3 * 1, 49 - 45 / 3 * 1)
Cpk = MIN(2, 1.3333)
Cpk = 1.33
The process is capable since the Cpk >= 1.33
