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 "4 circular spigots" softkey.
5. 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).
6. Enter the approximate diameter of the spigot in "Øspigot" (see step
4, "Measuring one circular spigot manually").
7. Enter the infeed value in "DZ" to determine the measuring depth.
8. Under "Angle offs." select entry "Yes" if you want alignment to be
performed with coordinate rotation.
- OR -
Under "Angle offs." select entry "No".
9. Enter the setpoint angle.
The angle entered here refers to the 1st axis of the working plane
(X/Y plane). This input field only appears if you specified "Yes" for
"Angle offs."
10. Specify setpoint positions X0 and Y0.
These determine the point of intersection of the lines connecting
the spigot center points.
11. 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.
12. Then move the tool approximately to the center of the second,
third, and fourth spigot and press the "Cycle Start" button.
The tool automatically contacts 4 points in succession around the
spigot outside walls. After successful completion of measurement,
measured values P2, P3, and P4 are stored and the softkeys "P2
stored", "P3 stored", and "P4 stored" become active.
