Measuring X-Axis Straightness and Flatness Simultaneously
The straightness and flatness for X can be measured simultaneously by adding a second measuring target
to the bottom of the spindle ram. The targets come with a 3-piece post set, so a shorter post may be used
to adjust the target height to pick up the red laser.
1. Attach a second measuring target to the
bottom of the spindle ram with a short post.
Adjust the target height to pick up the red
laser.
2. Turn on the rotation for both laser planes.
The Gold Laser (top left) measures X-Axis
Straightness and the Red Laser (bottom left)
measures Flatness.
3. The target readings are sent wirelessly to a
laptop computer, where our Machine Tool
Geometry software records them. Select the
axis, enter the length of travel and number
of points, and ensure the targets are pointed
at the laser. Hit the RECORD button and
the Machine Tool Geometry software
records both targets’ data simultaneously
and plots out straightness.
4. Continue to move the column to each point
and hit Record. After the data has been
taken, return the column to the home
position.
5. The X-Axis results show a Straightness
error of .0007 in. TIR and a Flatness error of
.0006 in. TIR. The slope of the Best Fit line
is .0003 in/ft, which means the X-Axis is
sloping UP relative to the table.
