Orientation Transformation And Orientable Tool Holders - Siemens SINUMERIK 840DE sl Function Manual

Programming offset automatically
As the offset is transferred automatically from the currently active zero offset on the orientation
axes, the effects of zero offset on rotary axes are always the same, both with and without active
transformation. Automatic take-over of offset from zero offset is possible via machine data
MD24590 $MC_TRAFO5_ROT_OFFSET_FROM_FR_1 = TRUE (Offset of rotary
transformation axes from NPV) for the first machine data, or MD24690
$MC_TRAFO5_ROT_OFFSET_FROM_FR_2 = TRUE (Offset of rotary transformation axes
from NPV) for the second transformation in the channel.
Note
There is no difference between a zero offset on the orientation axes programmed during active
transformation and the previous offset.
If automatic transfer of offset has been activated and a rotary axis offset is programmed at the
same time, the programmed offset value takes priority.
Orientable toolholder with additive offset
On an orientable toolholder, the offset for both rotary axes can be programmed with the system
variables $TC_CARR24 and $TC_CARR25. This rotary axis offset can be transferred
automatically from the zero offset effective at the time the orientable toolholder was activated.
Automatic transfer of offset from zero offset is made possible via the following machine data:
MD21186 $MC_TOCARR_ROT_OFFSET_FROM_FR = TRUE (offset of TOCARR rotary axes
from NPV)

Orientation transformation and orientable tool holders

Note
Orientation transformation and orientable tool holders can becombined.
The resulting orientation of the tool is produced by linking the orientation transformation and the
orientable tool holder.
