Aligning the plane

You can measure an inclined plane of a workpiece in space and determine rotation angles α
and β. By subsequently performing coordinate rotation, you can align the tool axis
perpendicular to the workpiece plane.
In order to determine the position of the plane in space, three different points are measured
along the tool axis. To vertically align the tool axis, the "Swivel" function or the 5 axis
transformation (TRAORI) must be set-up at the machine.
In order to be able to measure the plane, the surface must be flat.
Requirement
You can insert any tool in the spindle for scratching when measuring the workpiece zero
manually.
An electronic workpiece probe is inserted in the spindle and activated when measuring the
workpiece zero automatically.
Procedure
108

2. Press the "Workpiece zero" and "Align plane" softkeys.
The "Align plane" window opens.
3. Select "Measuring only" if you only want to display the measured
values.
- OR -
Select the desired zero offset in which you want to store the zero point
(e.g. basis reference).
