Experimental Investigation and Optimization of Process Parameters Used in the Silicon Powder Mixed Electro Discharge Machining of Ti-6Al-4V Alloy Using Response Surface Methodology

Ti-6Al-4V is extensively used as a piece of the avionics, auto, and biomedical fields; however is a difficult to machine material. Electro Discharge machining (EDM) is seen as one of the most ideal approaches to manage machining Ti-6Al-4V combination, since it is a noncontact electro-thermal machining method, and it is self-ruling from the mechanical properties of the readied material. In EDM, dielectric plays important role in machining operation. In present paper silicon powder suspended plus kerosene is used as dielectric to explore the effect of these dielectrics on the execution criteria such as material removal rate (MRR) and roughness (Ra) in the midst of machining of titanium combination (Ti-6Al-4V). Peak current, pulse on time, pulse off time and powder included into dielectric liquid of EDM were picked as methodology parameters to think about the PMEDM execution with respect to MRR and Ra. The examinations were finished in organizing mode on an exceptionally made exploratory set up developed in laboratory. The ideal qualities for execution parameter were found by performing analysis and suggested ideal conditions have been verified by conducting confirmation experiments.
