2.6 Measuring workpiece zero
If you store the workpiece zero in a work offset, changes to the
coordinate system or axis positions might be necessary in the
following cases.
•
Correcting the work offset causes the workpiece coordinate
system to rotate, after which the tool can be aligned
perpendicularly to the plane.
•
Correcting the work offset necessitates positioning of the rotary
axis in order to align the workpiece parallel with the coordinate
system
Activation windows help you to adapt the coordinate system and the
axis positions.
You stored the workpiece zero in a work offset that was not active
during measurement.
When you press the "Set WO" softkey, the activation window opens
asking whether you want to "Activate work offset xxx now?".
Press the "OK" softkey to activate the corrected work offset.
Rotating the workpiece coordinate system makes it necessary to
realign the tool to the plane.
The activation window asking whether you want to "Position
measuring probe perpendicular to plane?" is displayed.
Select "Yes" if you want to swivel into the plane.
The query "Positioning by swiveling! Retract?" appears.
Select the retract method you want to use.
Press the "Cycle Start" key.
When the axis has been retracted the tool is realigned with the help of
the swivel cycle.
You can now measure again.
