In swivel systems with 2 rotary axes, a particular plane can be
reached in two different ways. You can choose between these two
different positions in the "Direction" parameter. The +/- corresponds to
the larger or smaller value of a rotary axis. This may affect the
working area.
When the swivel data set is set up, the entries in the "Direction"
parameter determine for which rotary axis you can select each of the
two settings.
Please refer to the machine manufacturer's instructions.
If one of the two positions cannot be reached for mechanical reasons,
the alternative position is automatically selected irrespective of the
setting of the "Direction" parameter.
To avoid collisions, you can use the 5-axis transformation (software
option) to retain the position of the tool tip during swiveling. This
function must be enabled in the "Follow-up tool" parameter when the
"Swivel" function is set up.
Please refer to the machine manufacturer's instructions.
Press the "Misc." and "Transformation" softkeys.
Press the "Delete values" softkey to restore the initial state, i.e. to
zero the values.
This is done, for example, to swivel the coordinate system back to
its original orientation.
