EMC does constant velocity countouring on 3-axis cartesian machines.
(I think it also does it on hexapods.) It does an approximation on machines
with mixed rotary and cartesian axes, as it doesn't know the distance
between the joints. (Maybe it could do this, it just needs some added
code in the kinetics reoutines.)

As to whether it is important, it depends on what you are doing. If you
are drilling holes in instrument panels, it is not very important. If you
are carving molds, it can be very important, as it affects surface finish.
