7. Enter the approximate diameter of the spigot in "Øspigot" (see step
4, "Measuring one spigot automatically").
8. Enter the infeed value in "DZ" to determine the measuring depth.
9. Under "Angle offs.", select the "Coor. Rotation" entry.
- OR -
Under "Angle offs.", select entry "Rotary axis A, B, C".
10. Enter the setpoint angle.
The angle entered here refers to the 1st axis of the working plane
(X/Y plane).
11. Specify the position setpoints (X1/Y1) for the center point of the
first hole.
The input fields are only active if you have selected the angle
offset via coordinate rotation.
12. Press the "Cycle Start" key.
The tool automatically contacts 4 points in succession around the first
outside wall of the spigot. When measurement has been successfully
completed, the center of the spigot is determined and the "P1 stored"
softkey becomes active.
13. Then move the tool approximately to the center of the second
spigot and press the "Cycle Start" key.
The tool automatically contacts 4 points in succession around the
second outside wall of the spigot. When measurement has been
successfully completed, the "P2 stored" softkey becomes active.
14. Press the "Set WO" or "Calculate" softkey.
Calculate
The angle between the line connecting the center points and the
reference axis is calculated and displayed.
With "Set WO", the center point of the first spigot now corresponds to
the position setpoint. The calculated rotation is stored in the work
offset.
1. Attach a 3D probe type tool to the spindle.
2. Move the tool until it is approximately at the center of the first
spigot.
3. In "Machine Manual" mode, select the "Meas. workp." softkey.
4. Press the "Spigot" softkey.
Press the "3 circular spigots" softkey.
