Abstract

Abstract: Great complexity and randomness exist in micro-electrical discharge machining (micro-EDM) process. Considering the limitations of molecular dynamics model and numerical model based on heat transfer theories in studies on machining mechanism of micro-EDM, a hybrid modeling method in which the two-temperature model and molecular dynamics simulation model were integrated was used to construct the machining model for the anode in micro-EDM process, and the corresponding parallel simulation platform was built based on MPI technology. In this simulation model, a heat source was placed in the electron system to mimic the thermal action of the discharge channel on the anode material, and furthermore, by analyzing temporal-spatial evolutions of temperature and stress in the anode material and temperature in the electron system, different machining mechanisms of anode material were revealed correspondingly when different amounts of energy were input.
