Question

Which of the following option is correct regarding anvils of ‘adjustable type gap gauges’?

(a) Gauging anvil has only sliding movement

(b) Gauging anvil has only rotating movement

(c) Gauging anvil has both sliding and rotating movement

(d) Anvils are of non-adjustable type

This question was addressed to me during a job interview.

This interesting question is from Plain Gauges in portion Limits, Fits and Gauges of Engineering Metrology

Answer 1

The correct choice is (a) Gauging anvil has only sliding movement

To explain: In adjustable type gap gauges, gauging anvils are adjustable endwise in the horse shoe frame. The gauging anvils of adjustable type snap gauges have only sliding movement that is no rotating movement for adjustment. A sufficient distance should be present between ‘Go’ and ‘No Go’ anvil.
