Titanium Alloy (Ti6Al4V) is considered hardest and strongest alloys in the current manufacturing industries. It is utilized in medical implant devices due to its superior physical and chemical properties, including impressive strength-to-weight ratio, high resistance to corrosion, and lightweight characteristics. The influence of different cutting tool materials and machining parameters has attracted considerable interest on the surface roughness of this alloy. This is mainly because Titanium alloy has lower thermal conductivity and forms a strong chemical affinity together with the cutting tool surface under high-temperature conditions. The objective of this study is to investigate the impact of various cutting tool of materials and influencing machining parameters on the surface roughness of biomedical-grade Titanium alloy. Taguchi method is employed to optimize the parameters for machining of biomedical grade Titanium alloy. The results showed that cutting speed and feed rate exert a very greater influence on the surface roughness of Titanium alloy. With a Tungsten Carbide insert cutting method, the obtained surface roughness value was notably high, whereas in experiment 7, the value reached was 0.957
