With this setting, the axial offset of the rotary axis is taken account of in the transformation up to the SZS. The
axial offsets of the rotary axis included in the SZS frames are entered into the transformation frame as rotation.
This setting is only effective if the transformation frame has been configured.
Frame expansions:
The expansions described below are only valid for the following machine data settings:
MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 1
MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 2
The selection of transformation TRANSMIT produces a virtual geometry axis, coupled by way of the rotary axis,
which is merely included in the contour frame but does not have a reference to an axial frame. The geometric
value results from the rotation of a rotary axis. All other geometry axes accept their axial components when the
transformation is selected.
Translations:
When selecting TRANSMIT, translations of the virtual axis are deleted. Translations of the rotary axis can be
taken into account in the transformation.
Rotations:
Rotation before the transformation is taken over.
Mirroring:
Mirroring of the virtual axis is deleted. Mirroring of the rotary axis can be taken into account in the transformation.
Scaling:
Scaling of the virtual axis is deleted. Scaling of the rotary axis can be taken into account in the transformation.
