Location & approach

By car

From highway “A1”

At intersection “Dortmund/Unna” change to highway “A44” in the direction of Dortmund, which becomes the B1. Take the exit “Dortmund-Dorstfeld”, in the direction of “Universität”. Turn right onto “Planetenfeldstraße”, after 850 meters turn left onto “Otto-Hahn-Straße”. After 1 km turn right onto “Marie-Curie-Allee”, after 550 meters keep slightly right to stay on “Baroper Straße”.

From highway “A45”

Take the exit “Dortmund-Eichlinghofen”, in the direction of “Universität”. Turn right onto “Stockumer Straße”, after 800 meters turn left onto “Baroper Straße”.

Please use parking lot entrances 40 or 41 for access to the “Maschinenbau III” building or entrance 42 for access to the Experimental Hall.

By bus and train

Arrival with DB to Dortmund or Bochum central station.
From Dortmund central station take the interurban train line S1 in the direction of Düsseldorf and get off at the stop “Dortmund Universität S”.

a) Surface properties, b-d) Additive manufacturing of cooling channels: procedure and preliminary tests

Funding	German Research Foundation (DFG)

Contact	Anna Komodromos M. Sc.

Hot stamping is used in sheet metal forming in order to exploit the increase in strength due to quenching. For this purpose, cooling channels, which are usually produced using machining processes, are integrated in the tools. The production of hot stamping tools using directed energy deposition (DED) is intended to enable the channels to be positioned close to the surface. Therefore, the properties of the additively manufactured surfaces in terms of roughness, hardness, friction, and residual stresses are first characterized (see Figure a). The initially rough surface after DED is then leveled by ball burnishing. This induces compressive residual stresses, which increase with higher rolling pressures. To manufacture the cooling channels, open cooling channel structures are milled into a solid material and then sealed using DED (see Figure b-d). When designing the cooling channels it is necessary to achieve a compromise between the additive manufacturability and the surface fraction, which effectively contributes to the heat balance on the tool surface.
