A rotary axis offset can, for example, be entered by compensating the oblique position of a
workpiece in a frame within a frame chain. As a rule, this offset can also be included in the
transformation as an offset in the rotary axis. A c axis offset, as in the figure above, then
leads to corresponding x and y values.
MD24905 $MC_TRANSMIT_ROT_AX_FRAME_1 = 2
MD24905 $MC_TRANSMIT_ROT_AX_FRAME_2 = 2
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 rotations. This setting is only effective if the transformation
frame has been configured.
Frame expansions:
The expansions described below are only valid for the machine data
$MN_FRAME_GEOAX_CHANGE_MODE = 1
$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:
On selecting transmit, translations of the virtual axis are deleted. Translations of the rotary
axis can be taken into account in the transformation.
Rotations:
Rotations before the transformation are taken over.
Mirrorings:
Mirrorings of the virtual axis are deleted. Mirrorings of the rotary axis can be taken into
account in the transformation.
Scalings:
Scalings of the virtual axis are deleted. Scalings of the rotary axis can be taken into account
in the transformation.
