Online tool radius compensation

Function
When the longitudinal axis of the tool and the contour are perpendicular to each other, the
offset can be applied as a length compensation to one of the three geometry axes (online tool
length compensation).
If this condition is not fulfilled, then the offset quantity can be entered as a real radius
compensation value (online tool radius compensation).
Enable
The online tool-radius offset is released via the machine data:
MD20254 $MC_ONLINE_CUTCOM_ENABLE (enable online tool radius compensation)
Switching on/switching off
An online tool radius compensation is activated and deactivated by means of the G commands
FTOCON and FTOCOF (in the same way as an online tool length compensation).
Parameter assignment
The parameters of the online tool offset are set by PUTFTOCF or PUTFTOC.
The parameter <ToolPar> (wear parameter in which the correction value is to be calculated)
must be set for the online tool radius compensation as follows:
<ToolPar> = 4
