4. Then the L-106X Laser Translation Stage is used to translate (move the
laser with very little angular change) the laser plane so both targets read
close to zero, usually the tolerance is .010 in. (0.25 mm). This means
the laser is now on the centerline of the machine.
5. Step 4 may need to be repeated a few times to get the laser aligned
(bucked-in) to the reference points.
6. Mount an A-1519-2.4ZB Target on the log carriage (or fixture to
simulate the carriage) horizontally and adjust so that it detects the laser
beam. A second A-1519-2.4ZB can be mounted vertically on the
carriage to measure flatness/level (this setup is similar to the machine
tool setup in image shown in Figure 20). Now both A-1519-2.4ZB
measuring targets on the carriage are zeroed at a location next to the
laser.
7.
To measure the straightness, the carriage is moved at user-specified
intervals and any deviations from zero are noted or recorded. Since the
readings update in real time, the target can be used as a digital indicator
and the point can be brought into alignment by adjusting it until the
reading is zero.
8. To measure the flatness/level, the vertical target is used in the same
manner and at the same time as the horizontal target. Both the flatness/level and straightness can
be measured and aligned at the same time.
Checking Support Rollers for Squareness
The goal is to ensure the rollers supporting the logs are perpendicular to the machine centerline to prevent
“wandering” of the logs to one side or the other.
With the same setup as above, make up a fixture that is mounted over the roll. It has a post that is
approximately 12 in. long and the target is mounted horizontally, which will be used to “sweep the roll”
