Abstract
This paper describes the development of a pulse generator for nano EDM using a capacity coupling method. To obtain discharge craters of nanometer diameter, a pulse generator was coupled to the tool electrode by a capacitor. Since the influence of the stray capacitance in the electric feeders can be eliminated, the discharge energy can be minimized to accomplish nano EDM. This method also allows non-contact feeding of electric current to the rotating spindle, minimizing the run-out of the tool electrode. To control the gap width, the gap voltage was also measured using the capacity coupling method.
