Setting the datum in the intersection of multiple holes:
Preposition the touch probe approximately in the
center of the hole
Hole is to be probed automatically: Define by soft
key
Probing: Press the machine START button. The
touch probe probes the circle automatically.
Repeat the probing procedure for the remaining
elements
Terminate the probing procedure and switch to the
evaluation menu: Press the
EVALUATE
soft key
Datum : In the menu window, enter both
coordinates of the circle center, confirm with the
SET DATUM
soft key, or write the values to a table
(see "Writing measured values from the touch
probe cycles in a datum table", page 436, or see
"Writing measured values from the touch probe
cycles in the preset table", page 437)
Terminate the probing function: Press the
END soft
key
Setting a center line as datum
Select the probe function: Press the PROBING soft
key
Position the touch probe at a position near the first

Position the touch probe at a position near the
second touch point
Start the probing procedure: Press the NC Start
button
Datum : Enter the coordinate of the datum in the
menu window, confirm with the

soft
key, or write the value to a table (see "Writing
measured values from the touch probe cycles in a
datum table", page 436, or see "Writing measured
values from the touch probe cycles in the preset
table", page 437.
Exit the probing function: Press the
END key
After you have measured the second touch point,
you can use the evaluation menu to change the
direction of the centerline. You can choose by soft
key whether the datum or zero point should be set
in the reference axis, minor axis or tool axis. This can
be necessary if, for example, you would like to save
the measured position in the reference and minor
axis.
