The diameter and center point of the hole are calculated and
displayed.
The set position of the center point is stored as the new zero point if
you have selected "work offset". The tool radius is automatically
included in the calculation.
1. Attach a 3D probe type tool to the spindle.
2. Move the tool until it is positioned approximately at the center of
the first hole.
3. In "Machine Manual" mode, select the "Meas. workp." softkey.
4. Press the "Pocket/Hole" softkey.
The "Holes" window opens with new vertical softkeys.
5. Press the "2 holes" softkey.
6. Specify whether you want "Measurement only" or in which work
offset you want to store the zero point (as described under
"Measuring an edge manually", step 5).
7. Enter the approximate diameter in "Øhole" (see step 4, "Measuring
two holes manually".
8. Under "Angle offs.", select the "Coor. Rotation" entry.
- OR -
Under "Angle offs.", select the "Rotary axis A, B, C" entry.
9. Enter the setpoint angle.
10. Specify the position setpoints (X1/Y1) for the center point of the
first hole.
X1 and Y1 are only active, if the "Coor. Rotation" entry is selected.
11. Press the "Cycle Start" key.
The tool automatically contacts 4 points in succession around the first
inside wall of the hole. When measurement has been successfully
completed, the "P1 stored" softkey becomes active.
12. Then move the tool approximately to the center of the hole and
press the "Cycle Start" button.
The tool automatically contacts 4 points in succession around the
second inside wall of the hole. When measurement has been
