In this research, the effects of viscosity of lubricant in cold work extrusion process were investigated. The experimental evaluation was carried out by using cold work plane strain extrusion apparatus with a pair of 45‐degree die half angle and a symmetrical workpiece (billet). The billet material was annealed pure aluminum, A1100. The analytical evaluation was carried out using a visioplasticity method. The testing lubricant is RBD palm olein, RBD palm stearin and palm fatty acid distillate. The results were compared with the additive free paraffinic mineral oil. The result shows that palm oil has advantage in reducing the extrusion load. We confirmed that palm oil showed satisfactory lubrication performance, as compared to additive free paraffinic mineral oil. |
