ABSTRACT:
A system, method, and computer program for designing an electrode for electric discharge machining, comprising identifying a cavity in a three-dimensional design; calculating a direct negative boolean of said cavity to define a general form for an electrode; determining an orbit path for said electrode, wherein said orbit path has a plurality of vertices corresponding to a plurality of instances with said three-dimensional design; subtracting a plurality of instances from said general form for said electrode whereby an orbit gap is removed from said general form electrode; and applying a constant face offset to said general form for said electrode having said orbit gap and appropriate means and computer-readable instructions.
