The tool nose radius compensation value during execution is the sum of
the geometry offset and the wear offset.
OFR=OFGR+OFWR
The imaginary tool nose direction may be set for either the geometry
offset or the wear offset.
However, the last designated direction later is effective.
A offset number is specified with the same T code as that used for tool
offset. For details, see Subsec. II–14.1.2.
NOTE
When the geometry offset number is made common to the
tool selection by the parameter LGT(No.5002#1)setting
and a T code for which the geometry offset and wear offset
number differ from each other is designated, the imaginary
tool nose direction specified by the geometry offset number
is valid.

However, the direction specified by the wear offset number
becomes enabled depending on the parameter WNP
(No.5002#7) setting.
The range of the offset value is an follows :
Increment system metric system Inch system
IS–B 0 to"999.999 mm 0 to"99.9999 inch
IS–C 0 to"999.9999 mm 0 to"99.99999 inch
The offset value corresponding to the offset number 0 is always 0.
No offset value can be set to offset number 0.
