A gage block with an exaggerated flatness
of
error is illustrated in foldout-11. You can see
contact
that there are no interference bands on a portion
interference
of the optical flat because this portion of the
bands
gage block and optical flat ________ ________ are
error
_______ and are _______ to each other.
54
flat

In most instances, the exaggerated condi-
interference
tions of foldout-11 do not exist. In some in-
bands
stances the mating surfaces will not have a
straight
________ ________to produce evenly spaced bands.
constant
In some instances the mating surface will not be
slope
__________ . Therefore, the bands will not be
evenly

When you compare the flatness errors at A,
number
B, and C in foldout-13 with the errors at D, E,
interference
and F, you will realize that the ______ ______
bands
at the top exist because the surfaces are
one
______ , and those at the bottom exist because
half
the surfaces are _________ .

The interference bands at A and D appear
to be the same; However, they were produced
point
by different types of surfaces. One surface
is ____________ and the other is ____________.

To determine the ________ in the _________
of the two blocks in foldout-14, you will use
heights
the formula:
h= /
