The device that is proposed is a low cost simplification on the industrial sinking electro-discharge machine. What is proposed is to remove the controlling actuators (usually stepping motors or servomotors) altogether and instead use the electromotive force of the spark discharge itself to drive a simple solenoid coil connected to the spark discharge in series, pulling the sparking electrode out of contact with the machined material when a discharge occurs. This cycle is then biased by gravity or another constant force (such as a spring), making the process self-sustaining and requiring very little external control circuitry to operate. This device would be useful for imprecise uses of EDM (such as burning out broken taps) and due to the simplicity of design and fabrication, priced affordably.
