The objective of this work is to determine the effectof some of the main process parameters of electro-discharge
machining, in terms of both the surface finish and process productivity. Among the different factors involved in
EDM process, the present study is oriented to the analysis of current intensity and depth of penetration, as some of
the process parameters with a greater effect on material removal by electro-discharge machining. From the
experimental results obtained in this work, it is deduced technical guidelines that can be applied to select the
optimum process conditions for this workpiece material.
