Abstract: Unique properties of titanium alloys (such as high strength-to-weight ratio, heat and corrosion resistance, shock resistance and erosion resistance) make them important materials in industries. However, poor machinability poses considerable problems in fabrication of components from titanium alloys. Therefore, to machine titanium alloys cost effectively still remains a challenge. In this paper, Rotary Ultrasonic Machining (RUM) of titanium alloy (Ti-6Al-4V) has been investigated. Four tools with different specifications (diamond grit size, diamond concentration and metal bond type) are used to drill holes in titanium alloy workpieces. The cutting force, surface roughness on machined holes and rods and tool wear are compared.
