Summary
In the presented research, Heat Transfer Modelling of Electric Discharge Machining (E.D.M.) is investigated, in detail. Two new models along with existing ones are presented. One of the new models is based on the uniformly-distributed-point-sources assumption. The other one is an approximate but general model, involving time variation of heat source and its radius. When simpler models are used, the agreement with the experimental results is less. More complex models with channel expansion required excessive computational times. Aggreement with the experimental data is shown to be satisfactory for all cases.
