The zero plane corresponds to the tool plane (G17, G18, G19) including the active work
offset (G500, G54, ...). Rotations of the active work offset and the rotary axes are taken
into account for manual swiveling.
The "Swivel Manual" function only writes rotations either in the workpiece reference
($_WPFRAME) or in the active work offset.
You can use the "Swivel Manual" function not only for machining, but also for setting-up.
– You can bring the machine into the initial position using the "Basic setting" softkey and
the <CYCLE START> key. If the actual work offset does not include a rotation, then
the rotary axes of the swivel data set are moved to zero. The tool is located vertically
to the machining plane.
If you want to use the actual swiveled plane as the reference plane for setting up your
workpiece, you must define this plane as the zero plane.
– With "Set zero plane" the actual swivel plane in the active work offset is stored as the
zero plane. As a result, the rotations in the active work offset are overwritten.
– With "Delete zero plane", the rotations in the active work offset are set to zero.
Note
The overall coordinate system does not change with "Set zero plane" or "Delete zero
plane".
