Article Preview

An axisymmetric two-dimensional thermal model, whose boundary conditions are constantly changing both in magnitude and position, has been developed based on the basic principles of electrical discharge machining (EMD) using the finite element method (FEM). The thermal load of heat flux are applied on the surface of the workpiece using the programming language Python provided by ABAQUS FEM software. The temperature field distribution, diameter, and depth of the crater are simulated by this model. Finally, the model is validated by comparing the theoretical crater diameter with the experimental crater diameter obtained from the experimental setup developed in the laboratory.
