Abstract

Machining process of titanium alloys as aerospace material that has extremely strength to weight ratio and resistant to corrosion at high-elevated temperature, become more interesting topic. Quality of machining process is presented by performance of tool and surface quality of titanium alloys. The turning parameters evaluated are cutting speed (55, 75, 95 m/min), feed rate (0.15, 0.25, 0.35 mm/rev), depth of cut (0.10, 0.15, 0.20 mm) and tool grade of PVD carbide tool. The results that tool life show three patterns: rapidly increase at the initial stage, gradually increased at the second stage and extremely increased at final stage. The trend lines of surface roughness have are the surface roughness value is high at first machining after then regularly decreases. At the second stage, the surface roughness is remained stable and followed by decreasing at final stage of tool life.
