ABSTRACT
For a highly stochastic and multi-physical phenomenon-based machining process like micro-electrical discharge machining (µEDM), studying the computational and simulation models is necessary. A 2D axisymmetric model for crater formation during the µEDM process was studied in this paper to compare the simulation and experimental results. Arbitrary Lagrangian-Eulerian method (ALE), also called the moving mesh method, is used to compute the flow of material resulting from melt pool formation. The numerical model presented in the model gives a similar trend for the crater diameter as compared with the experimental results with good accuracy on brass and copper as two different materials. The temperature distribution inside the melt pool formation describes the effect of thermal conductivity on the crater formation.
Keywords: Arbitrary Lagrangian-Eulerian, Multi-physics, Crater, µEDM, Melt pool.
