Experimental studies on duplex turning of Titanium alloy (Ti-6Al-4V)

Duplex turning process is a novel cutting operation in which two cutting tools are applied from opposite directions simultaneously to cut the desired material from the surface of the rotating workpieces. In present work, experimental investigations were made to measure the distribution of cutting forces on primary and secondary cutting tools and average surface roughness (Ra) for the Duplex Turning process. The Titanium alloy (Ti-6Al-4V) has been used as workpiece material for experimentation. The cutting parameter such as cutting speed, feed rate, primary depth-of-cut (D1) and secondary depth-of-cut (D2) were taken as control parameters. The experimental results show the effectiveness of the Duplex turning in term of better surface quality and reduction in cutting forces as compared to normal turning.
