Abstract

In the present research, the wire cross section is considered for analysis to evaluate the peak temperature obtained by the wire during machining. The crater shape and crater area on the wire have been estimated from the temperature profile which can be used to evaluate the wire erosion rate. Gaussian heat flux is considered in the model as it gives better results compared to other approaches as available in literature. In the present work, we have considered the latent heat of melting of brass wire as it is a very important factor in the thermal modeling of EDM because latent heat signifies the consumption of the amount of supplied heat in the phase change of the wire material. The developed model successfully predicted the temperature profiles across the wire cross section. It will be useful in the prediction of wire rupture during adverse process conditions.
