Question

What is the use of ‘No Go’ gauges?

(a) Check a single element of a feature

(b) Check several dimensions simultaneously

(c) Check roundness and size at the same time

(d) Check location and size at the same time

The question was asked in an interview.

My question is from Gauge Design topic in division Limits, Fits and Gauges of Engineering Metrology

Answer 1

Right answer is (a) Check a single element of a feature

To explain I would say: ‘No Go’ gauge should check only one feature at a time. A separate ‘No Go’ gauge is needed for each different individual dimension. ‘Go gauges’ are complex gauges can check several related dimensions simultaneously.
