The study of the dependence between successive discharges is the key factor towards better understanding of the complex and random nature of EDM. Data dependent systems (DDS) which addresses such dependence are applied to model and analyze the EDM process. The DDS model of an EDM surface provides an exponential crater which upon integration with the classical thermal model and empirical evidence yields expressions for erosion rate and surface integrity. The DDS modeling of pulse voltage/current signals provide a measure of gap conditions. The damping ratio associated with a discriminating frequency (32 KH//z) is small for arcing. An analysis relating the damping ratio with characteristics of a pulse provide the information required for control.
