Web16 okt. 2024 · USL=24; LSL=18;Ave=21.5;Standard Deviation = 0.75. As per the given calculator, we get the values of Cp as 1.33 and Cpk as 1.11. What do we infer from this ? 1.Cp value of 1.33 indicates that the process is quite capable. 2.However, Cpk value of 1.11 conveys that the process sigma is 3.33 . WebHow is USL calculated? To calculate the USL value, type each of the three required inputs into separate cells. For example, we’ll place the LSL (60) in cell B1, the capability index (2.25) in B2, and the standard deviation (1.5) in B3. Hit Enter, and Excel will automatically calculate the USL of your process: 80.25. How is D4 calculated?
