“…Reducing the wear and the friction coefficient is the target for current investigations to integrate dry metal forming in industrial mass production. Dry deep drawing of various sheet metals was investigated for example by controlled selective oxidation of cold work steel surfaces [3], by using ceramic tools [4] or by macro-and microscopically modified surfaces of a deep drawing tool [5]. Comprehensive tribological aspects in dry forming were presented by [6].…”

Abstract. Regarding the optimization of forming technology in economic and environmental aspects, avoiding lubricants is an approach to realize the vision of a new green technology. The resulting direct contact between the tool and the sheet in non-lubricated deep drawing causes higher stress and depends mainly on the material combination. The tribological system in dry sliding has to be assessed by means on the one hand of the resulting friction coefficient and on the other hand of the wear of the tool and sheet material. The potential to generate tailored tribological systems for dry metal forming could be shown within the investigations by using different material combinations and by applying different laser cladding process parameters. Furthermore, the feasibility of additive manufacturing of a deep drawing tool was demonstrated. The tool was successfully applied to form circular cups in a dry metal forming process.

Cold working without lubricant, 2,3) or with limited lubricants 4) were also discussed. As another solution, the authors proposed a new lubrication method using a porous layer formed on the workpiece surface.…”

Lubrication is an important parameter in cold working of steels. Metal soap on phosphate coating is the most commonly used lubrication system in industries at present, but the technique is less productive and environmentally hazardous. The authors proposed an alternative lubrication process which makes use of porous layer formed on the surface of the workpiece by oxidization and chemical reduction in the previous paper. The technique, due to the porous layer, enables to hold more liquid lubricant on the surface and consequently to decrease the friction. This research expands the range of application of this technique. The porous layer is applied to three types of steels containing different levels of carbon and its effects are analyzed under three lubrication conditions; unlubricated, machine oil and grease, by ring-compression test. Another important condition, compression speed is investigated by using two types of equipments, a hydraulic press (low speed) or a mechanical press (high speed). This study proves that the porous layer technique is applicable to a range of types of steels reducing the friction coefficient, and at the same time provides some insights to explain the mechanics of the technique. The lubrication effects are explained by the thickness of lubricant held at the interface between the die and the surface of workpiece.

“…However, these always provide a smaller limiting drawing ratio, compared to lubricated processes. 26 Another approach proved that the ceramic materials ZrO 2 -WC and Al 2 O 3 -TiC are suitable for dry metal forming processes. In this case, the limiting drawing ratio is close to the value within lubricated processes.…”

In metal forming, lubricants are still used to prevent corrosion, to reduce friction, wear and tool load as well as to protect the workpieces and intermediates. In economic and ecological points of view, the challenge is the avoidance of lubricant usage. Within this article we define the term of dry metal forming, a technology which contributes an approach to establish green technology in mass production. Regarding this, the benefits of this technology are shown. Three different approaches exist to achieve a dry forming process: ceramic tools, self-lubricating coating systems and hard material coatings. Concerning this matter, the state of research in dry metal forming is reviewed within this paper.
