Machineable wax problem

Hello All,
I read this group every day and it is amazing how
erudite some of the contributors are! I have a simple
problem that, perhaps, cannot be solved. On the other
hand, maybe someone has a solution.
I do a lot of jewelry prototyping in machineable
wax
which is then burned out of a mold and cast in
precious
metal. The problem is this: I spend as much time
digging wax residue (chips) out of the final wax
carving as I do milling the piece. If I cut plastic,
then the milled carvings have almost no residue to dig
out. Unfortunately, the plastic doesn't burn out as
well as wax.
Anybody on the group know of a material that will
cut cleanly and burn out as well? Any other
suggestions
will be appreciated. I've even tried building a dam
around the wax and cutting in water. Nothing seems to
work!
