5 Programming: Tools
Between two program blocks with different radius
compensations (RR and RL) you must program at least
one block without radius compensation (that is, with R0).
Radius compensation does not come into effect until the
end of the block in which it is first programmed.
You can also activate the radius compensation for
secondary axes in the working plane. Program the
secondary axes too in each following block, since
otherwise the TNC will execute the radius compensation
in the principal axis again.
Whenever radius compensation is activated with RR/RL
or canceled with R0, the TNC positions the tool
perpendicular to the programmed starting or end
position. Position the tool at a sufficient distance from
the first or last contour point to prevent the possibility of
damaging the contour.
Entering radius compensation
When you program a path contour, the following dialog question is
displayed after entry of the coordinates:
Radius comp.: RL/RR/no comp. ?
<
To select tool movement to the left of the
contour, press the RL soft key, or
To select tool movement to the right of the
contour, press the RR soft key, or
To select tool movement without radius
compensation or to cancel radius
compensation, press the ENT key.
To terminate the dialog, press the END key.
