Note
Wear and setting-up values of active tools cannot be deleted (essentially the same as the
delete behavior of D or tool data).
3.13.3

Special handling of tool offsets

The evaluation of the sign for tool length and wear can be controlled using setting data
SD42900 to SD42960.
The same applies to the behavior of the wear components when mirroring geometry axes or
changing the machining plane, and also to temperature compensation in tool direction.
Wear values:
If reference is made to wear values in the following, then this should be understood as the sum
of the actual wear values ($TC_DP12 to $TC_DP20) and the sum offsets with the wear values
($SCPX3 to $SCPX11) and setting-up values ($ECPX3 to $ECPX11).
Information about summed offsets, see Function Manual Tool Management.
Setting data
SD42900 $SC_MIRROR_TOOL_LENGTH
SD42910 $SC_MIRROR_TOOL_WEAR
SD42920 $SC_WEAR_SIGN_CUTPOS
SD42930 $SC_WEAR_SIGN

Command to delete additive offsets
T number of the tool
D number of the tool cutting edge
All additive offsets of the cutting edges <d> of the tool <t> are deleted.
All additive offsets of all cutting edges of tool <t> are deleted.
All additive offsets of all cutting edges of all tools of the TO unit are deleted (for
the channel in which the command is programmed).
Delete status
Value: Meaning:
0 Deletion was successfully completed.
- Offsets have not been deleted (if the parameter settings specify ex‐
actly one tool edge), or not deleted completely (if the parameter
settings specify several cutting edges).
Mirroring of tool-length components and compo‐
nents of the tool base dimension.
Mirroring of wear values of the tool-length compo‐
nents.
Evaluating the sign of the wear components as a
function of the cutting edge position.
Inverts the sign of wear dimensions.
