2.6 Measuring workpiece zero
Example 1:
Remachining on a cylinder head with 2 holes on an inclined plane.
1. Clamp the workpiece
2. Insert probes T, S, M and activate the required work offset.
3. Preposition workpiece
rotate rotary axes manually until the inclined surface is almost
perpendicular to the tool axis.
4. Manual swiveling
Select "direct" swiveling, "Teach rotary axes", and press "Cycle
start".
5. Manual swiveling
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 in AUTO.
Start the program with swivel zero.
Example 2:
Measuring workpieces in swiveled position. 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. But 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. Insert probes T, S, M and activate the required work offset.
