Active Tool Path Compensation
If edge radius / cutter radius path compensation is active (G41/G42), the
CNC automatically calculates the length corrections which are active in
the working plane with respect to the center point of the edge S by add-
ing/subtracting the correct radius to/from the theoretical edge tip based on
the current position of the cutting edge.

Fig. 5-12: Error-free machining with tool edge radius path compensation active.
With tool path compensation active the center point of the tool travels
along a path which is parallel to the programmed contour and is offset by
the tool radius.
