Measuring angles
You can also use the 3D touch probe system to measure angles in the
working plane. You can measure
• the angle between the angle reference axis and a workpiece side, or
• the angle between two sides.
The measured angle is displayed as a value of maximum 90°.
To find the angle between the angle reference axis and a side of the workpiece:
Select the BASIC ROTATION probe function.
ROTATION ANGLE =
If you will need the current basic rotation later, write down the value that appears under ROTATION ANGLE.
Make a basic rotation with the side of the workpiece (see Section “Compensating workpiece misalignment”).
