Abstract
Over the past 15 years, numerous tribological systems for warm and hot aluminium sheet metal forming have been investigated by various researchers. Two previously disregarded aspects will be examined in this paper with an enhanced strip drawing test: the temperature influence on friction and wear performance in an extensive comparison of different lubricant classes in tool lubrication and the bonding performance of different lubricants to the die surface. In depth analyses of the coefficient of friction (COF) and wear performance (wear-free drawin) for nine different lubricants and additionally several different formulations / mixtures were carried out for sheet temperatures from 20 °C to 425 °C. Furthermore, approaches for future lubricant developments are given.
