Measuring a corner

You have the option to measure workpiece corners, which are defined by a right angle (90°)
or any inner angle.
Measuring a right-angled corner
The workpiece corner to be measured has a 90° inner angle and is clamped to the worktable
in any position. By measuring 3 points you can determine the corner point (point of intersection
of the angle side) in the working plane and angle α between the workpiece reference edge
(line through P1 and P2) and the reference axis in the working plane (1st geometry axis of the
working plane).
Measuring any corner
The workpiece corner to be measured has any (not right-angled) inner angle and is clamped
at any position on the worktable. By measuring four points you can determine the corner point
(point of intersection of the angle sides) in the working plane and angle α between the
workpiece reference edge (line through P1 and P2) and the reference axis in the working plane
(1st geometry axis of the working plane) and inner angle β of the corner.
Note
The coordinate system shown in the help displays is always in relation to the currently set
workpiece coordinate system.
Please be aware of this if you have swiveled or changed the WCS in any other form.
Precondition
You can insert any tool in the spindle for scratching when measuring the workpiece zero
manually.

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 P2.
4. Press the "Calculate" softkey.
The angle between the workpiece edge and reference axis is calculated
and displayed.
- OR -
Press the "Set ZO" softkey.
With "Set ZO", the workpiece edge now corresponds to the setpoint angle.
The calculated rotation is stored in the correction target that you have
selected.
