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 spigot automatically").
7. Enter the infeed value in "DZ" to determine the measuring depth.
8. Under "Angle offs." select entry "No".
- OR -
Under "Angle offs." select entry "Yes" if you want alignment to be
performed with coordinate rotation.
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 center point of the circle on which the center
points of the three spigots are to lie.
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 and
third 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 and P3 are stored and the softkeys "P2 stored"
and "P3 stored" become active.
13. Press the "Set WO" or "Calculate" softkey.
Calculate
The center point and the diameter of the circle on which the three
spigot center points lie are calculated and displayed. If you have
selected "Yes" in "Coor. rot.", angle α is additionally calculated and
displayed.
With "Set WO", the center point of the circle now corresponds to the
position setpoint. The calculated rotation is stored in the work offset.
