2.6.3 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
Load the probe and activate the desired work offset.
3. Pre-position the workpiece
Manually rotate the rotary axes until the inclined surface is almost perpendicular to the
tool axis.
4. Manual swivel
Select "direct" swivel, press the "Teach rotary axes" softkey and press <CYCLE START>
key.
5. Manual swivel
Apply "Set zero plane" to store the resulting rotations in the work zero.
6. Measure workpiece
Apply "Align plane" to correct the alignment of the workpiece.
7. Measure workpiece
Apply "2 holes" to define the rotation and offset in the XY plane.
8. Measure workpiece
Apply "Set edge Z" to define the offset in Z.
9. Start part program to remachine under AUTO.
Start the program with swivel zero.
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
Load the probe and activate the desired work offset.
