Abstract
Titanium alloys are newly developed advanced materials and are used in many of the industries including aerospace industries. The titanium alloys having excellent mechanical properties such as high strength to weight ratio, but the titanium alloys are having poor mach inability characteristics. In order to machining of titanium alloys some of the non conventional machining processes have been founded. Wire Electro Discharge Machining Process is one such advanced process is used to produce intricate shapes when the hard metals like titanium to be cut. In this work an investigation of the effect and optimization of process parameters on the material removal rate, surface roughness and kerf width of Ti-6Al-4V alloy with the help of wire electro discharge machining with zinc coated brass wire of diameter 0.25mm. The proper setting of these process parameters were determined by using Taguchi method using four factors each at three levels to know the behavior of responses such as material removal rate, surface roughness and kerf width. The optimization problem was formulated by using process parameters and process responses. Finally Modified TLBO Algorithm was implemented to find out the effective Wire EDM process parameters.
