Description
Friction is a kind of response occurring during relative motion in extrusion process. When friction occurs between tool and work piece fractionize with each other, surface expansion and high normal pressure occurs even at elevated contact temperature between work piece and die, which leads to adhesions(cold-weld), abrasion of die and work material. To reduce the friction, it requires a suitable lubricant. In the present work lubricant like Graphite, Molybdenum disulphide (MoS2) and Zinc stearate were tested in the extrusion process of AA6063 against Hot die steel (H13). The frictional factor has been determined for both un-lubricated and lubricated conditions. Experimental predicted values were compared with simulation
