Question

The nominal sizes of a GO/NO-GO snap gauge to inspect the diameter of a shaft that is $30.00 \pm 0.18$ mm is to be designed. A wear allowance of 3% of the entire tolerance band is applied to the GO side.
The nominal size of the GO gauge is (mm)

Solution

The correct option is A 30.1692
The tolerance band is 0.36 mm.

$Wear allowance = 0.03(0.36) =0.0108 mm$

GO gauge will inspect the maximum shaft diameter

$= 30.00 + 0.18 = 30.18 mm$

As the gauge wears, the dimension will increase allowing unacceptable parts, so the wear allowance is subtracted from it.

$Nominal GO size =30.18 - 0.018$

$= 30.1692 mm$
