When you pick the
key on the formula entry keyboard, the formula is
saved, and the build reference tool edit panel reappears, as shown in
Figure 6.59 (A) (page 6–71).
For the “
Absolute
” method, when you then pick the
Nominal
field, the build
reference tool uses the formula to acquire and “learn” the window tool’s “
X
Center
” coordinate value, and that value (263) appears as the X–axis value
in the
Nominal
field, as shown in Figure 6.59 (B). (Note that because the Y
and theta modes are disabled in this example, their values in the
Nominal
field remain 0.)
For the “
Delta
” method, which does not use a stored (“learned”) reference
value, picking the
Nominal
field will “exercise” the formula and return a
result, but it is not necessary to pick this field for the build reference tool to
operate properly.
At this point, the configuration process is completed for the build reference
tool in this example. The build reference tool is now ready to supply “
X
Center
” shift compensation to the two gage tools.
