Pre-positioning
If you want to preposition a rotary axis before measuring with "Align edge", move the rotary
axis so that your workpiece is approximately parallel to the coordinate system.
Set the relevant rotary axis angle to zero with "Set WO". Measurement with "Align edge" will
then correct the value for rotary axis offset or include it in the coordinate rotation and align
the workpiece edge precisely.
If you want to preposition your workpiece with "Align plane" prior to measurement, you can
set the required angular values under "Manual swivel". With "Set zero plane"you transfer the
resulting rotations into the active work offset.
The measurement with "Align plane" will then correct the value for the coordinate rotations
and precisely align the workpiece.
If the function "Swivel" is set up on your machine, we recommend that you perform swivel to
zero before starting measurement. In that way, you will ensure that the rotary axis positions
match the actual coordinate system.

Examples with manual swivel

Two typical examples demonstrate the interaction and the use of "Measure workpiece" and
"Manual swivel" when measuring and aligning workpieces.
First example
The following steps are required when remachining a cylinder head with 2 holes on an
inclined plane.
1. Clamp the workpiece
2. T,S,M
3. Pre-position the workpiece
4. Manual swivel

Load the probe and activate the desired work offset.
Manually rotate the rotary axes until the inclined surface is almost perpendicular to the
tool axis.
