ABSTRACT:
An electrode assembly for electrical discharge machining (EDM) a slot in a wall includes a plurality of laterally abutting individual electrodes having a collective perimeter configuration complementary with the slot. The electrodes define a collective height equal to the sum of their individual heights which may be substantially greater than the individual widths thereof for machining a correspondingly high aspect ratio slot in the wall.
