Measuring a hole
manually
1. Attach any tool for scratching to the spindle.
Jog
2. In "Machine Manual" mode, select the "Meas. workp." softkey.
3. Press the "Pocket/Hole" softkey.
The "Pocket/Hole" window opens with new vertical softkeys.
4. Press the "1st hole" softkey.
5. Specify whether you want "Measurement only" or in which work
offset you want to store the zero point (as described under
"Measuring a rectangular pocket manually", step 5).
6. Specify the position setpoints (X0, Y0) of the hole center point.
7. Traverse the tool to the first measuring point.
Save P1
8. Press the "Save P1" softkey.
The point is measured and stored.
Save P2
...
Save P4
9. Repeat steps 8 and 9 to measure and store measuring points P2,
P3, and P4.
Set WO
-or-
Calculate
10. Press the "Set WO" or "Calculate" softkey.
The diameter and center point of the hole are calculated and
displayed.
The set position of the center point is stored as a new zero point with
"Set WO". The tool radius is automatically included in the calculation.
Measuring a hole
automatically
1. Attach a 3D probe type tool to the spindle.
2. Move the tool until it is positioned approximately at the center of
the hole.
3. Prepare the measurement (as described under "Measuring a hole
manually", steps 2 to 6).
4. Enter a "Øhole" and the approximate diameter.
This limits the area for rapid traverse. If no diameter is entered,
travel starts from the starting point at measurement feedrate.
5. Enter an angle under "Probe angle".
With the probe angle you can turn the travel direction of the probe
any angle.
Cycle Start
6. Press the "Cycle Start" key.
The tool automatically contacts 4 points in succession around the
inside wall of the hole. When measurement has been successfully
completed, the "P0 stored" softkey becomes active.
