Abstract
In this experimental work, an attempt has been carried out to decide the optimized parameters namely diameter of wire, on/off pulse time, current, tension in wire for minimizing surface roughness (SR) & for maximizing MRR (metal removal rate) during machining by wire electrical discharge (WEDM) process of Titanium Grade 2 (Ti Gr 2) alloys. Ti Gr 2 alloys are widely employed in fabrication of various aerospace components because of their low weight ratio, high strength and superior resistance to corrosion. This paper discusses in detail about optimizing process parameters of WEDM including SR and MRR related with the corner machining mechanism employing Taguchi technique. Ti Gr 2 alloy components were machined using WEDM at various process control combinations obtained by means of Taguchi technique algorithm. The optimized process parameters were experimentally observed to yield high quality of surface finish, increased corner accuracy & high rate of material removal.
