In "flat D number " structure _TNUM has no significance. Here, only _KNUM (for D) and
_DLNUM are relevant.
Example 1: (without _TENV)
The wear of length 1 is to be corrected additively for tool T7 with D2. The tool environment is
to be the environment currently active (= measuring environment).
Relevant data:
_TNUM=7 _KNUM=0100002 _CHBIT[6]=0
Example 2: (without _TENV)
For tool T8 with D3, the wear of the length assigned to measuring axis _MA for this tool type
and setting (G17, G18, or G19 etc.) is to be corrected additively.
The tool environment is to be the environment currently active (= measuring environment).
Relevant data:
_TNUM=8 _KNUM=3 _CHBIT[6]=0 _MA=1
Example 3: (without _TENV)
For tool T5 with D2, the additive offset of DL=3, active in the length as defined for measuring
axis _MA, is to be corrected additively.
The tool environment is to be the environment currently active (= measuring environment).
Relevant data:
_TNUM=5 _KNUM=1001002 (or =1000002)_DLNUM=3 _CHBIT[6]=0 _CHBIT[8]=0 _MA=1
Example 4: (with TENV)
The wear of length 1 or the tool and D number stored in tool environment "WZUMG1" is to
be corrected additively (T and D not directly known).
Relevant data:
_TNUM=0 _TENV= "WZUMG1" _KNUM=2100000 _CHBIT[6]=0
Example 5: (with TENV)
For tool T stored in tool environment "WZUMG2" but specific D number D2, the wear of the
length assigned to measuring axis _MA for the stored tool type and stored setting (G17, G18,
or G19) is to be corrected additively.
Relevant data:
_TNUM=0 _TENV= "WZUMG2" _KNUM=2001002 (or _KNUM=2000002) CHBIT[6]=0
_MA=2
