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
5. Manual swivel
6. Measure workpiece
7. Measure workpiece
8. Measure workpiece
9. Start part program to remachine under AUTO.
Second example
Measuring workpieces in swiveled states. The workpiece is to be probed in the X direction
even though the probe cannot approach the workpiece in the X direction because of an
obstructing edge (e.g. due to clamping elements). However, with a swivel movement, the
measurement in the X direction can be replaced by a measurement in the Z direction.
1. Clamp the workpiece.
2. T,S,M

Operating Manual, 03/2010, 6FC5398-7CP20-1BA0
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.
Select "direct" swivel, press the "Teach rotary axes" softkey and press <CYCLE START>
key.
Apply "Set zero plane" to store the resulting rotations in the work zero.
Apply "Align plane" to correct the alignment of the workpiece.
Apply "2 holes" to define the rotation and offset in the XY plane.
Apply "Set edge Z" to define the offset in Z.
Start the program with swivel zero.
Load the probe and activate the desired work offset.
