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.
Requirement
You can insert any tool in the spindle for scratching when measuring the workpiece zero
manually.
- OR -
An electronic workpiece probe is inserted in the spindle and activated when measuring the
workpiece zero automatically.
