Add the two
V
readings together and divide by 2 (average the two
V
values). Add the two
H
readings
together and divide by 2 (average the two
H
values). These are the
V
and
H
Near
-Bore
target
Set
Points.
16.
Using the L-102 Beam Translator, adjust the laser beam until the R-1307 displays the target
V
and
H
Near Bore
Target
Set Points The laser is now centered to the
Near
Bore
and any mounting errors
have been eliminated by the NORMIN method.
17.
Move the T-218/T-225L to the
Far Bore
and insert it in the normal position. Write down the
V
and
H
readings (NORMal).
18.
Invert the target and take another reading. Write down the
V
and
H
readings (INverted).
19.
Average the two
V
values and the two
H
values to create the
V
and
H
Far
-
Bore Target
Set Points.
20.
Measure the distance from the L-111 posts to the mid-point of the T-218 in the
Near Bore
. This is
D1
. Then measure the distance from the mid-point of the T-218 in the
Near Bore
to the mid-point of
the T-218 in the
Far Bore
. This is
D2
.
21.
Calculate the
V
and
H
Laser
Set Points using this formula: -1*(D1/D2) Target Set Point
Far Bore
(from Step 19).
22.
Turn the L-111 Coarse
Angular
Pitch and Yaw
adjustment knobs (see Figure 16) until the R-
1307) reads close to the
V
and
H
Laser
Set
Points. When the adjustment becomes too
difficult with the L-111, use the
V
and
H
angular
adjustments on the L-706 (see Figure 18) until the
values equal the
V
and
H
Laser
Set Points
from
Step 21.
23.
Move the T-218/T-225L back to the
Near Bore
and repeat Steps 15 and 16.
24.
Repeat Steps 13-20 until the
V
and
H
target Set
Points are zero at the
Near
and
Far Bore
s. The
laser is now aligned (bucked-in) to the two end
bores.
Remote Buck-in Note:
This procedure can be performed much faster
if the Remote Buck-In Formula (Set Point = -1*(Far reading * (L1/L2) is
used each time you do the Laser buck-in. If the distance from the laser to the target in the Near Bore is more
than 10 percent of the distance from the target in the Near Bore to the target in the Far Bore, it will be
necessary
to follow the Remote Buck-In procedure (see Appendix C on Page 42).
