Measuring a pocket and hole

You can measure rectangular pockets and one or more holes and then align the workpiece.
Measuring a rectangular pocket
The rectangular pocket must be aligned at right-angles to the coordinate system. By
automatically measuring four points inside the pocket, its length, width and center point can
be determined.
Measuring one hole
The workpiece with the hole to be measured is clamped to the work table in any position. In
the hole, four points are automatically measured, and from this measurement, the diameter
and center point of the hole are determined.
Measuring two holes
The workpiece with the two holes to be measured is clamped to the work table in any position.
Four points are automatically measured in both holes and the hole centers are calculated from
them. Angle α is calculated from the connecting line between both center points and the
reference axis, and the new zero point that corresponds to the center point of the 1st hole is
determined.

1. Prepare the measurement (see steps 1 to 6 above).
2. Approach measuring point P1 with the workpiece probe and press the
<CYCLE START> key.
This starts the automatic measuring process. The position of measuring
point 1 is measured and stored.
The "P1 stored" softkey becomes active.
3. Repeat the operation to measure and store points P2 and P3.
If you are measuring a corner not equal to 90°, repeat the procedure to
measure and store point P4.
4. Press the "Calculate" softkey.
The corner point and angle α are calculated and displayed.
- OR -
Press the "Set WO" softkey.
The corner point now corresponds to the setpoint position. The calculated
offset is stored in the offset target that you have selected.
