3.13.5 3D tool radius compensation
3.13.5.1 Selecting 3D tool radius compensation for 3D circumferential milling (CUT3DC,
CUT3DCD, ISD)
The 3D tool radius compensation (3D TRC) for the 3D circumferential milling without taking
limitation surfaces into account is selected with the modally effective G command CUT3DC or
CUT3DCD.
754
Number of the channel in which the online tool offset is to take effect.
Note:
Only required if the offset is not to take effect in the active channel.
Data type: INT
Number of the spindle for which the online tool offset is to take effect.
Note:
Only required if the offset is to be applied to a non-active grinding wheel rather than
the active tool that is currently in use.
Data type: INT
Activate online tool offset
The command must be programmed in the channel in which the online tool offset
is to be activated.
Deactivate online tool offset
The command must be programmed in the channel in which the online tool offset
is to be deactivated.
Note:
On FTOCOF, the axis does not move further out for the tool offset. However, the
value calculated with PUTFTOC/PUTFTOCF remains in the cutting-specific offset
data.
To finally deactivate the online tool offset, the tool (T...) must again be selected/
deselected after FTOCOF.
