Study on Influence of Stray Inductance in Micro EDM Using Electrostatic Induction Feeding Method
In the micro EDM method by electrostatic induction feeding, a pulse generator is coupled to the tool electrode by a capacitor, since the negative influence of the stray capacitance in the circuit can be eliminated, and the discharge energy per pulse can be minimized, thereby realizing discharge craters of nanometer order. However, there is still the stray inductance in the discharge circuit, other than the stray capacitance. In this study, in order to examine the influence of the stray inductance, experimental investigation was conducted.
