13. Press the "Set WO" or "Calculate" softkey.
Calculate
The spigot center points are connected diagonally and the intersection
point of the two connecting lines calculated and displayed If you have
selected "Yes" in "Coor. rot.", angle α is additionally calculated and
displayed.
With "Set WO", the intersection point now corresponds to the position
setpoint. The calculated rotation is stored in the work offset.
You can measure an inclined plane of a workpiece in space and
determine rotations α and β. By subsequently performing coordinate
rotation, you can align the tool axis perpendicular to the workpiece
plane.
In order to determine the position of the plane in space, three different
points are measured along the tool axis.
To align the tool axis in the perpendiculary you require a swiveling
table or swivel head.
In order to be able to measure the plane, the surface must be flat.
1. Attach any tool for scratching to the spindle.
2. In "Machine Manual" mode, select the "Meas. workp." softkey.
3. Press the "Align plane" softkey.
4. 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).
5. Traverse the tool to the first measuring point that you want to
determine.
6. Press the "Save P1" softkey.
7. Then move the tool to the second and third measuring point and
press the "Save P2" and "Save P3" softkeys.
