Abstract

High production rates at minimum cost will also be achieved by selecting correct cutting tool geometry for a particular combination of work material and cutting tool. Problem facing in precision turning is how to minimize tool wear in order to obtain good accuracy of geometrical part and surface finish. In this study the effect of changing the rake angle of insert carbide geometries to the wear level was investigated. The tungsten carbide insert type of DNMA 432 was used as cutting tool. FCD500, a difficult-to-cut ductile cast iron, was chosen as work material. There were seven simulations using Deform-3D were carried out at various tool geometries combination, whilst the cutting speed, feed rate and depth of cut were kept constant at 200 m/s, feed 0.35 mm/rev, and 0.3 mm respectively. The carbide insert geometries were designed in order to produce -15,-10, -5 deg (negative rake angle), 0 and +5, +10, +15 deg (positive rake angle) using pre processor of Deform-3D. Changing the rake and clearance angles will influence the wear depth of the inserts. The results also show that increase in rake angle will reduce the cutting force and temperature, therefore reduced the wear depth. On the other hands, decreasing clearance angle will caused bigger contact area between the clearance face and work piece surface, consequently, increase the tool wear.
