Abstract

This paper investigates the tool wear morphology and chip segmentations in end milling of titanium alloy Ti–6Al–4V using uncoated WC-Co inserts under dry conditions. CNC Vertical machining centre 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 and chip segmentations are comprehensively investigated. Scanning electron microscope is utilized for these purposes. Several type of wear, such as flank wear, crater wear, chipping, etc, is successfully disclosed. Primary and secondary chip serrations also appear on the chip segmentations.
