The Effects of Shape and Tool Material on Aluminum Sheet Spinning

Abstract:

In this paper the effects of shape and tool material on the output parameters on spinning of aluminum sheets are investigated. To achieve this purpose, four kinds of roller tools with the same shapes and with different materials including mild steel, ertalon, polyamid and caoutchouc were used and some parts were spun by the same geometric form; moreover, in order to investigate the effects of roller nose radius on output parameters such as surface smoothness and thickness distribution, three caoutchouc roller tools with different nose radius were used at the same condition. The results show that using a caoutchouc roller tool for spinning of aluminum sheets leads to the best surface smoothness, while using a steel tool because of its roughness is not suitable. Ertalon and polyamid roller tool have a high rate of wearing. Furthermore, in the constant feedrate by increasing of roller nose radius the contact area between roller and workpiece is increased and surface smoothness is followed, relatedly.
