Abstract
Ti6Al4V is an alpha-beta alloy which low density, high strength, high bio-compatibility and good corrosion resistance. These properties makes it a special attraction to the aerospace, rail and biomedical industries as a possible replacement to steel based alloys. In this study, the Taguchi methodology was employed for the optimisation of the process parameters. The three process parameters considered are; the feed rate (0.25-0.5mm/rev), depth of cut (0.3-0.75 mm) and the cutting speed (20 m/min to 100 m/min). Taking the surface roughness as the response of the designed experiment, the experimental produced four experimental runs that was validated via physical experimentations and statistically. The
results show that cutting speed has the highest contribution to surface roughness (71.27%) followed by the feed rate (15.46) while the depth of cut has the least contribution (13.27%). The combination of process parameters which produced the least surface roughness is feed rate 0.250mm/min, depth of cut 0.75 mm and cutting speed of 100 m/min. It is envisaged that the findings of this study will be helpful for machinist and material developers in the determination of the feasible range of process parameters that will ensure a good surface finish during the turning operation of Ti6Al4V.
