As titanium alloy (Ti 3Al-2.5V) has high strength and stiffness with excellent corrosion resistance, it finds its application in aerospace and industrial application. Ti grade 9 is hard, and we have adopted CO2 laser beam techniques to machine Ti grade 9. We have chosen oxygen and nitrogen gases as assisted gases. Of the various laser beam energy techniques, carbon dioxide laser beam is found to be one of the emerging trends in machining complicated and circuitous parts with maximum accuracy and in less time. Design of experiment is represented by Taguchi’s L9 orthogonal array. Two sets of experiments were conducted with oxygen and nitrogen as assisted gases. Material removal rate and surface roughness were calculated and optimized using group Taguchi relational analysis. It is found that surface finish and material removal rate are improved by using nitrogen gas for machining titanium alloy (Ti 3Al-2.5V) using CO2 laser.
