It allows tools of somewhat different diameter to be used without changing
the
program. The CNC has to know which side of the specified line to cut on.
The toolpath is specified as the actual dimension of the part, and is not
offset
by the tool radius, as you would usually do when writing G-code by hand

Andrew,
In this particular instance, I think the only thing that needs to be
addressed is whether you cutter comp off a flat xy plane or off the rotary A
axis. Cutter comp must take place with your rotary table centerline axis
being your zero point rather than a flat surface. This may be the reason the
three panels don't line up.
