Abstract

This paper investigates the effect of the uncoated carbide inserts in end milling of titanium alloy Ti-6AI-4V under dry conditions. CNC Bridgeport VMC machining was employed during the experimentations. Sandvick end milling of uncoated tungsten carbide inserts were chosen as the cutting tools. The effect of cutting parameter, i.e. cutting speed, feed, and axial depth of cut on tool wear morphology, surface roughness and chip segmentations are comprehensively investigated. Scanning electron microscope is utilized for these purposes. Flank wear has been considered as the criteria for tool failure and the wear was measured using a scanning electron microscope. Primary and secondary chip serrations also appear on the chip segmentations. The surface of titanium alloy is easily damaged during machining operations due to their poor machinability. Surface roughness generally increases with the increase of feed.
