Answer and Explanation:
The computation is shown below:
Upper specification limit is
= 5 + 0.1
= 5.1 mm
Lower specification limit is
= 5- 0.1
= 4.9 mm
The process cabability index is
= min(USL - mean ÷ 3 × standard deviation , mean - LSL ÷ 3 × standard deviation)
= min((0.1 ÷ 3 ×0.02) , (0.1 ÷ 3 × 0.02))
= min(1.67,1.67)
= 1.67
Since Upper specification is 5.1 mm
And, the Mean line is 5 mm
So, the upper specification lies at a distance for
= 5.1 - 5
= 0.1 mm
Standard deviation is 0.02 mm
Hence, upper specification lies at
= 0.1 ÷ 0.02
= 5
This standard deviation from the means
