A study on economic tooling concepts for dry deep-drawing using environmentally benign volatile lubricants

Abstract. Dry processes represent promising approaches in forming technology to improve environmental aspects and human health by avoiding harmful substances and additives of conventional lubricants. Among many different approaches for dry forming investigated within the priority program SPP 1676, this paper addresses the use of volatile media as lubricants such as CO2 or N2. These volatile media are introduced directly into the interstice between sheet metal and tool surface via microinjectors. Indeed, this does not contradict the principle dry forming approach, as dry forming is defined as a process in which no residues are left on the surfaces [1]. This is ensured by the complete evaporation of the volatile media. The general feasibility of this novel tribological system has already been demonstrated in previous research work. However, despite good tribological results, the manufacturing costs of the required tool inserts and the media consumption per component are not yet economically competitive with conventional tribological systems. Therefore, this paper focuses on new designs of dry deep-drawing tools utilising volatile lubricants, considering the economics of different manufacturing processes.
