brent some cnc shops that do that
type of work will use a software
engraving program,or a 3-d cad-cam
software program such as mastercam
the software will create surfaces in 3-d
then create tool paths over the surfaces
then it is ball milled.cost for shop time is
around 70.00 per hour for a small shop
to program and set up for that small
quantity would be around 500 bucks.
