Hi,
How does to select USL and LSL limits?
For example,
I have observation results of 30 Re is 3.43, 3.27 ,3.19, 3.17,3.17, 3.19, 3.19, 3.24, 3.1, 3.12 ,3.25, 3.2, 3.35, 3.2, 3.2, 3.22, 3.23, 3.18, 3.19, 3.31, 3.18, 3.08, 3.18, 3.17, 3.23, 3.19, 3.25, 3.26, 3.23, 3.18
mean = 3.2117, STD = 0.07
Company datasheet provided for Re is 3.08 and production tolerances +/- is 7.50%
——–
to find Cpk how do I calculate USL and LSL values?
