Keywords:
Titanium alloy (Ti 6Al 4V), Surface roughness (Ra), Material removal rate (MRR)Abstract
Wire cut electrical discharge machining (WEDM) is a modification of electrical discharge machining (EDM) which has been widely used for machining of materials when precision is important. The optimization of process parameters in WEDM to obtain highest degree of dimensional accuracy and surface finish is one of the most challenging tasks. A zinc coated wire and brass wire of 0.25mm diameter were used as tool electrode. This work has been established as a comparison of the two wires in terms of surface roughness and MRR on Titanium alloy (Ti-6Al-4V) and experimentally studied. The purpose of this study is to investigate the effect of parameters like Pulse ON time, Pulse OFF time, Dielectric pressure and Peak current on Surface roughness (Ra) and Material Removal Rate (MRR). Analysis of Variance was employed to determine level of significance of the machining parameters and mathematical model is developed by means of linear regression analysis.
