PRECISION MEASURING AND GAGING - OD1642 - LESSON 1/TASK 2
SETTING DIMENSIONS ON THE SNAP GAGE.
3 Take the gage block selected for the NO GO dimension and
check it against the setting (5) (figure 15, view C).
If the NO GO
dimensions are incorrect, place the gage block in place and turn the other
adjusting screw (3) until the NO GO dimension (5) is set.
4 After adjusting the gage for proper dimensions with the
master precision piece (6) in place (view C), tighten the locking screws (2)
(view D). Recheck to make sure that the dimensions have not changed before
the gage is used to check the workpiece.
