Abstract

Aerospace components from titanium alloys require the greatest reliability and satisfied surface integrity requirement. However, during machining of titanium alloys, the machined surface is easy damage because of the difficult-to-machine material and poor machinability. The aims are to investigate the surface integrity of Ti-6%A1-4%V ELI when machining under dry cutting condition. The results showed that the surface roughness values recorded were more affected by feed rate and nose radius geometry. Surface roughness was high value at the first machining followed by decreasing. Work hardening beneath the machined surface caused higher hardness than based material, on the other hand, over-aging caused the softening on machined surface of titanium alloy. Changing orientation of microstructure and 2 μm of white layer on the machined surface was found when turning at cutting speed of 95 m/min, feed rate of 0.35 mm/rev and depth of cut of 0.10 mm.
