Impact of Nano-Fluids in Turning of Ti6Al4V under Different Side Rake and Clearance Angles

Titanium Alloy grade 5 is a magnificent material in the Aerospace, Automotive, and Shipbuilding industries. It has high strength and low weight tendency, making it more reliable in defence-related industries. The poor heat-carrying capacity of this material influences the cutting tool performance through thermal degradation, making it difficult to shear. Mainly Phase alteration generates strain hardening which, implies the poor machinability index. This study investigates the impact of nanofluid coolants, side rake angle, and clearance angle on the machinability of Titanium Alloy 5 during turning operations. Using a constant cutting speed 65 m/min, depth of cut 0.5 mm, and feed rate 0.28 mm/rev under an envelope of three nano-fluids were evaluated along with varying tool angles. The cylindrical surface finish and tool wear, analyzed to measure the performance of the experimental research. Furthermore, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) analysis identified the optimal parameters for enhanced machining at a side rake angle of 15 ⁰ clearance angle of 12 ⁰ and Graphene oxide based nanofluid coolant. Graphene oxide nanoparticles act as good heat carriers and reduce the detrimental effect of thermal degradation on machining performance. These findings improve the turning efficiency and cylindrical surface finish with the least tool wear. The experimental investigation gives optimised parameters like side rake angle 15 ⁰ , clearance angle of 12 ⁰ with Graphene oxide added nanofluid coolant proves to get superior performance in Titanium alloy grade 5 turning operation.
