RL: Radius compensation
F: Feed rate
M: Miscellaneous function
Interpretation of the programmed path
With FUNCTION PROG PATH, you decide whether the control will
apply the 3-D radius compensation only to the delta values, just as
before, or rather to the entire tool radius. If you activate FUNCTION
PROG PATH, the programmed coordinates exactly correspond to
the contour coordinates. With FUNCTION PROG PATH OFF, you
deactivate this special interpretation.
