5-8 EM-506 (N-07/03)
shipped from the factory zeroed from the centerline of
the ram with the gage assembly at .00” position.
Note:
The locking screw knob spins freely unless it is
pulled out. This allows the knob to rest against
the backgage face, thus preventing the finger
from being unlocked while the assembly is in
position on the gage bar.
PROGRAM GAGE POSITIONS
Now that the gage assemblies and the gage fingers have
been positioned left-to-right and vertically, the backgage
can be programmed for its front-to-back positions.
The actual position of the gage in relation to the tooling
is selected when entering a program into the Control.
This procedure is described under in SECTION 7,
"GAGE PAGE". The actual gage dimension from the
centerline of the tooling to the gage surface is
determined by two program inputs, flange dimension
and gage allowance. The actual gage dimension input is
the sum of gage allowance and flange dimension. See
Figure 5-15.
FIGURE 5-15 Figuring actual gage dimension
Normally the control will position the gage bar relative
to the ram centerline for a gage surface that is 4.000”
(102mm) in front of the face of the gage bar. This is
correct when using standard gage finger assemblies with
3.000” (76mm) long fingers, along with tooling that is
centered on ram centerline. Shorter gage assemblies
require negative offset and longer assemblies require
positive offset values. (
Note: Put this offset in the finger
offset field on the Gage Page.)
The 1/4” (6.4mm) gage finger can also be used as a sheet
support as shown in Figure 5-16, for lightweight sheets.

WORK SUPPORTS
Work supports for light gauge material are available as
optional equipment. They are intended to be used in the
rear of the bed when long backpieces (which droop away
from the gage surface) are formed. These supports attach
to rear dovetail slots in the bed and should be positioned
at same height as the top of lower die. Figure 5-17 shows
a typical work support setup. Make sure backgage bar
and gage finger assemblies clear the work supports.
