Z-Axis Flatness and Straightness, Z-X and Z-Y Squareness, Z-W (in X)
Parallelism, Z-W (in Y) Parallelism
The final axis check is Z-Axis flatness and straightness, which provides the squareness to the X-Axis and
the squareness to the Y-Axis. In addition, the parallelism for Z-W (in Y) and Z-W (in X) can be
determined.
1. Leave the laser in position and re-
position the targets. To measure Z-Axis
flatness, use the red laser plane with
Target #1 on the table.
2. For straightness, mount Target #2’s post
into the side hole in the magnetic base to
pick up the green laser plane. Adjust the
pole length for Target #2, turn on the
green laser and zero the display.
Repeat for Target #1 and the red laser
plane. Now you’re ready to measure.
