Question

What is the main use of contour gauges?

(a) Check shape of irregular work

(b) Check profiles

(c) Check distance between surfaces

(d) Check position of work

I had been asked this question in class test.

The origin of the question is Plain Gauges in division Limits, Fits and Gauges of Engineering Metrology

Answer 1

Correct choice is (a) Check shape of irregular work

The best explanation: Contour gauges are generally used to check dimensional accuracy and shape of irregular work e.g. radius gauges are used to check fillet shape. Simple contour gauges are used for thread pitches, form gear tooth profiles etc.
