Taking a measurement for each inner bore
1.
Take a reading on the near target with the target in the normal position (see Figure 15). Write down
the
V
and
H
Readings (NORMal).
2.
Invert the target and take another reading (see Figure 17). Write down the
V
and
H
Readings
(INverted).
3.
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). The
V
and
H
averages are True Bore
Alignment values (see Appendix A – The NORMin Method, beginning on Page 37).
Target Set Point Example:
Formula:
(N+I) /2
NORMal readings V: .0089
H: -.0056
INverted readings V: .0140
H: .0015
Target Set Points:
V: (.0089 + .0140) /2 =
.0115
H: (-.0056 + .0015) /2 =
-.0021
Laser Set Point Example:
Formula: -1*(D1/D2)*Target Set Point Far Bore
(from Step 19)
D1= 4.5
D2= 24.25
Far Bore Target Set Points:
V=.0115
(from Target Set Point example)
H=.0021
Laser Set Points:
V: -1*(4.5/24.25) * .0115 = -.19 * .0115 =
-.0022
H: -1*(4.5/24.25) * -.0021 = -.19 * -.0021 =
+.0004
