The application of Ti–6Al-4V alloy in the fields of biomedical and aerospace industries attracts the manufacturing engineers to understand the behavior of alloy during machining. Ti–6Al-4V alloy posses high specific strength and corrosion resistance and besides its advantages they poses challenges in machining due its low thermal conductivity nature. The heat generated during machining is dissipated through cooling medium and cutting tool. Considering the situation detailed experiments are planned for turning of Ti–6Al-4V alloy with varies cutting speed, feed rate and depth of cut. The cutting tool is cooled with the process of evaporative cooling technique by using the water soaked banana fiber pad along with fan and flooded coolant. This method dissipates 39.51% of heat generated during cutting operation at parameter combination of 1200 rpm cutting speed, 1.5mm/rev feed rate and 0.6 mm depth of cut. The lowest average surface roughness (Ra) is recorded at parametric combination of 1200 rpm cutting speed, 0.25mm/rev feed rate and 0.6 mm depth of cut for banana fiber cooled tool. The use of banana fiber resulted in lesser Ra of 0.42μm. Further studies with multi-pad evaporative cooling facilitate for increased tool heat dissipation.

The application of Ti–6Al-4V alloy in the fields of biomedical and aerospace industries attracts the manufacturing engineers to understand the behavior of alloy during machining. Ti–6Al-4V alloy posses high specific strength and corrosion resistance and besides its advantages they poses challenges in machining due its low thermal conductivity nature. The heat generated during machining is dissipated through cooling medium and cutting tool. Considering the situation detailed experiments are planned for turning of Ti–6Al-4V alloy with varies cutting speed, feed rate and depth of cut. The cutting tool is cooled with the process of evaporative cooling technique by using the water soaked banana fiber pad along with fan and flooded coolant. This method dissipates 39.51% of heat generated during cutting operation at parameter combination of 1200 rpm cutting speed, 1.5mm/rev feed rate and 0.6 mm depth of cut. The lowest average surface roughness (Ra) is recorded at parametric combination of 1200 rpm cutting speed, 0.25mm/rev feed rate and 0.6 mm depth of cut for banana fiber cooled tool. The use of banana fiber resulted in lesser Ra of 0.42μm. Further studies with multi-pad evaporative cooling facilitate for increased tool heat dissipation.
