A Model of Micro Electro-discharge Machining Plasma Discharge in Deionized Water. Mujumdar, S. S, Curreli, D., Kapoor, S. G, & Ruzic, D. Journal of Manufacturing Science and Engineering, 136(3):031011, 2014.
Paper doi abstract bibtex For successful commercial adaptation of the μ-EDM (micro electro-discharge machining) process, there is a need to increase the process efficiency by understanding the process mechanism. This paper presents a model of the plasma discharge phase of a single discharge μ-EDM event in deionized water. The plasma discharge is modeled using global model approach in which the plasma is assumed to be spatially uniform, and equations of mass and energy conservation are solved simultaneously along with the dynamics of the plasma bubble growth. Given the input discharge voltage, current and the discharge gap, complete temporal description of the μ-EDM plasma during the discharge time is obtained in terms of the composition of the plasma, temperature of electrons and other species, radius of the plasma bubble and the plasma pressure.
