A study on the machining parameters optimisation of electrical discharge machining

The optimum selection of manufacturing conditions is very important in manufacturing processes as these ones determine surface quality and dimensional precision of the so-obtained parts. Thus, it is necessary to know, in advance, properties relating to surface quality and dimensional precision by means of theoretical models which allow to do some predictions taking into account operation conditions such as gap, dielectric fluid, penetration speed, etc. Manufacturing materials with non-conventional processes such as electrical discharge machining, shows really important aspects to study from the point of view of materials science, heat transmission, mechanics and manufacturing processes optimisation. This study is mainly focused on aspects related to surface quality and dimensional precision, which are one of the most important parameters form the point of view of selecting the optimum conditions of processes, as well as economical aspects. Functions making it possible to optimise parameters related to surface quality in such manufacturing processes will be obtained by means of using mathematical models that will allow us to select the optimum manufacturing conditions.
