Abstract: In this paper we attempt the cryogenic treated brass wire to machined titanium alloy,Cryogenic treated hard brass wire is used in production of high performance dies, punches, etc. Cryogenic treatment is a process of keeping the wire in cold environment to increase its wear resistance and relieving its residual stresses. Experimental observations are based on Taguchi Method to find the optimum process parameter. Titanium alloys Grade-2 are often employed in Aerospace industry components due to their outstanding mechanical properties. This project work will steer towards attaining higher machining efficiency by acquiring a higher Cutting Speed (CS), Material Removal Rate (MRR) and low Surface Roughness (SR) with low wire consumption and frequency of wire breakage and making comparative study of brass wire and cryogenic treated brass wire on titanium alloy (Grade 2) using CNC WEDM with cryogenic setup

Keywords: Wire Electric Discharge Machine (WEDM), Cryogenic Setup, Titanium alloy.
