You can measure workpieces with a 90° angle or with any other
angle.
•
Measuring a right-angled corner
The workpiece has a 90° corner and is in any orientation on the
work table. By measuring three points you can determine the
corner point in the working plane (X/Y plane) and angle α
between the reference edge on the workpiece (line through P1
and P2) and the reference axis (always the 1st axis in the working
plane).
•
Measuring any corner
The workpiece has any corner (not right-angled) and is in any
orientation on the work table. By measuring four points you can
determine the corner point in the working plane (X/Y plane), angle
α between the reference edge on the workpiece (line through P1
and P2) and the reference axis (always the 1st axis in the working
plane), and angle β in the corner.
1. Attach any tool for scratching to the spindle.
2. In "Machine Manual" mode, select the "Meas. workp." softkey.
3. Press the "Corner" softkey.
The "Corner" window opens with new vertical softkeys.
4. Press the "right-angled corner" softkey, if you want to measure a
right-angled corner.
- OR -
Press the "any corner" softkey, if you want to measure a corner
not equal to 90°.
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. Under "Corner", select the type of corner you want to measure
(e.g. outside corner) and its position (e.g. position 1).
7. Specify the setpoint of the workpiece corner (X0, Y0) you want to
measure.
8. Traverse the tool to the first measuring point P1 as shown in the
help display.
