Mousavi, A.A.MousaviBrosius, A.2020-03-252020-03-252015https://media.suub.uni-bremen.de/handle/elib/3082In order to achieve an efficient use of resources, a decreasing usage of lubricants is an important goal in forming processes. Therefore, a new approach for a lubricant free deep drawing process shall be realized. One basic element of this approach is the use of macro-structured tools in order to reduce the friction forces and control the material flow. This paper presents the basic process principles and the results of analytical investigations, FE-simulations and experiments for a process design without lubrication.4deinfo:eu-repo/semantics/openAccessDry formingDeep drawingta-C coatingMacro structuring620Artikel/Aufsatzurn:nbn:de:gbv:46-00104222-11
