In the cold forging of AA2014, friction at the die/billet interface plays a significant role. AA2014 metallic rings of height 8 mm with an outer diameter of 24 mm and inner diameter of 12 mm was upset between H13 steel dies to different levels of deformation. Different types of lubricants namely, grease, molybdenum disulphide, white grease, palm oil were employed at the die/ring interface and ring compression test was also conducted for un lubricated condition. The values based on the changes in the geometry after different levels of deformation were fit into Male and Cockroft calibration curves to estimate the friction factor (m). The values of friction factors determined from the experiments were given as input to the finite element package, Deform 2D. The results obtained from the finite element studies were compared with the experimental results. After validation, the research was extended by considering ring geometries of different sizes. The effect of the friction between the die/billet interface and geometry were studied on the flow of metal. The zone of minimum velocity of particles, defined as neutral plane was analyzed for different friction conditions and different geometries of the ring.
