ABSTRACT:
An EDM circuit arrangement incorporating a minimum-impedance electrical conductor assembly in a tubular form between an EDM pulse generator and a machining gap, the assembly having a first group of conductors connected between one terminal of the pulse generator and a tool electrode to conduct the machining pulses in one direction and a second group of conductors connected between the other terminal of the pulse generator to conduct the machining pulses in the opposite direction. An electrically nonconductive member contouring the tubular form and having these conductors mounted therein in mutually insulating and generally parallel and equally spaced relationship in an endless row, framing the tubular form, between its outer and surfaces and generally concentric therewith is provided. The conductors are arranged in such a manner that each of the conductors in the first group is axially aligned proximate with a conductor of the other group in the endless row.
