Machining characteristics of silane-treated wheat husk biosilica in deionized water dielectric on EDM drilling of Ti-6Al-4 V alloy

In this research, a novel attempt has been made using silane-treated wheat husk–derived biosilica water dielectric on machining Ti-6Al-4 V titanium alloy. The main aim of this investigation was to improve the machining behavior of Ti-6Al-4 V titanium alloy in electro discharge process using biosilica-activated deionized water dielectric. The biosilica particles had been prepared using thermo-chemical process from wheat husk ash biomass. The dielectric fluid was prepared using simple mixing process and ultrasonically stirred. The microdrilling process was done using a computerized EDM machine with recommended process variables. According to the study, the addition of biosilica particle of significant volume increased the material removal rate and tool’s life. The surface roughness also seemed lesser for biosilica-assisted nanofluid of significant volume. These machining characteristics that improved micro-EDM process could be used to machine high harder defense, automobile, and structural metallic material with high dimensional and functional quality.
