Abstract

Wear on the flank of a cutting tool is caused by friction between newly machined surface and the contact area on the tool, which plays predominant role in determining tool life. Detailed study on progression and wear mechanism at the cutting edge of CVD carbide tools were carried out at cutting speed of 55-95 m/min, feed rate of 0.15-0.35 mm/rev and depth of cut of 0.10-0.20 mm. The pattern of wear progression on the flank face of the carbide tools consist of three stages for all the cutting speed tested. Those are; extremely rapid wear at the initial stage, gradually increases at the second stage and rapidly increases at the final stage especially at high depth of cut (0.20 mm) and high feed rate (0.35 mm/rev). High feed rate and depth of cut would cause high temperature generated and consequently damaged the cutting edge. While low depth cut and cutting speed would cause the wear formation near to the nose radius. Machining at low cutting speed (low temperature generated) resulted in titanium alloy welded onto the cutting edge. Wear mechanism such as abrasive and adhesive wear were observed on the flank face. Crater wear due to diffusion was also observed on the rake race.
