EDM-ing (Electrical Discharge Machining). Sinking EDM is a stochastic process whereas the conditions of formation and evolution of each discharge depends on the outcome of preceding discharges. There is no known mathematical model of the Sinking EDM process due to the lack of complete definitions of interdependent non-linear probabilistic electrodynamic, thermoenergetic, hydrodynamic and thermochemical processes for a single discharge.
