17.3 Online tool radius compensation
General information
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).
Enabling of function
The online tool-radius offset is activated via the machine data:
MD20254 $MC_ONLINE_CUTCOM_ENABLE (enable online tool radius compensation).
Activation/deactivation
An online tool radius compensation is activated and deactivated by means of commands

defined limit values (e.g. velocity).
If a DRF offset and online offset are active simultaneously for an axis, the DRF offset is
considered first.
In case of the following channel-specific machine data is taken into account:

An acceleration margin can thus be reserved for the movement which means that the
overlaid movement can be executed immediately.
