Study and Optimization of Cutting Parameters Using RSM for High-Speed Precision Machining of Titanium Alloys

Titanium alloys Ti6Al4V largely used material in aerospace structural industries for its indispensable characteristics of the material for its good formability, strength, light weight and corrosion resistance. Most precision-machined components are made using titanium-based alloys in aerospace applications. The challenges in machining of titanium alloys remains the same and even tough during high cutting speed for precision milling of mating components . The titanium alloys are now grouped as difficult to machine due to its hardness and low thermal conductivity, where most of the heat generated in the cutting is passed to the cutting tool and results in tool wear. The optimum levels of high-speed precision finish machining of highly reactive material like titanium and its alloys is still unsolved. Optimization study of high-speed CNC machining parameters presented in this research paper are based on the experimental study on optimality conditions of the parameters like coolant flow rate, Spindle speed, tool feed rate and tool depth of cut on tool life for better surface smoothness in Titanium alloy precision CNC milling process.
