Well, actually I am assessing the competence of our inspection department and one of the questions on the exam is the following:
Which of the following would be the most appropriate inspection tool to measure a machined, .213” dia. hole +/- .010, in a .030” thick stainless steel plate?
a. Micrometers
b. Gage pin
c. Calipers
d. Bore gage
This is one question I was not sure about the answer, a gage pin makes sense, the bore gage too accurate and calipers seem good enough for the +/-.010" tolerance.
Suggestions are welcomed.
