15. COMPENSATION FUNCTION
215
When the options of tool geometry compensation and tool wear
compensation are selected, the offset values become as follows :

In this case, the tool nose radius compensation value is the sum of the
geometry or the wear offset value.
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–15.1.2.
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.
