PRECISION MEASURING AND GAGING - OD1642 - LESSON 1/TASK 2
FIGURE 27.
RING GAGES.
4 The use of the ring gage (figure 28 on the following page)
is an important function when checking the accuracy of parts. Proper use of
the ring gage requires a sensitive sense of feel by the individual
inspecting the finished parts.
5 To check the shank diameter of a pivot stud
(figure 28)
line the stud (view A) (1) up with the hole (2) and press it in
gently. If
the stud will not go in, the shank is too large. With the stud
in the hole
(view B), check the piece for taper and out-of-roundness by
sensing any
wobble.
6 After checking the part in the GO gage, check it in the NO
GO gage. The stud must not enter this gage to establish it as being between
the desired limits.
