Finding the angle between the angle reference axis and a
workpiece edge
U Select the probe function by pressing the PROBING
ROT soft key
U Rotation angle: If you need the current basic rotation
later, write down the value that appears under
Rotation angle
U Make a basic rotation with workpiece edge to be
compared (see "Compensating Workpiece
Misalignment with a 3-D Touch Probe" on page 387)
U Press the PROBING ROT soft key to display the angle
between the angle reference axis and the workpiece
edge as the rotation angle
U Cancel the basic rotation, or restore the previous basic
rotation
U This is done by setting the rotation angle to the value
that you previously wrote down
To measure the angle between two workpiece edges:
U Select the probe function by pressing the PROBING ROT soft key
U Rotation angle: If you need the current basic rotation later, write
down the displayed rotation angle
U Make a basic rotation with first workpiece edge (see "Compensating
Workpiece Misalignment with a 3-D Touch Probe" on page 387)
U Probe the second edge as for a basic rotation, but do not set the
rotation angle to zero!
U Press the PROBING ROT soft key to display the angle PA between
the workpiece edges as the rotation angle
U Cancel the basic rotation, or restore the previous basic rotation by
setting the rotation angle to the value that you wrote down
previously
