To position with radius compensation:
TOOL RADIUS COMP.: RL/RR/NO COMP.?
Select tool movement to the left of the programmed contour.
Select tool movement to the right of the programmed contour.
Radius compensation RR/RL is not in effect until the end of the block in
which it is first programmed.
Between two program blocks with differing radius compensation you must program at least one block without radius
compensation (that is, with R0).
Traverse with radius compensation RR, RL
The tool center moves to the left (RL) or to the right (RR) of the pro-
grammed contour at a distance equal to the tool radius. “Right” or “left”
is meant as seen in the direction of tool movement as if the workpiece
were stationary.
