  • Denkena, Berend; Gümmer, Olaf (Amsterdam : Elsevier, 2013)
    Within the Collaborative Research Centre 489 at the Leibniz Universitaet Hannover a new and innovative process chain for the manufacture of crankshafts is being investigated. By burr-free and near-net-shaped precision ...
  • Denkena, Berend; Dittrich, M.-A.; Uhlich, F.; Wichmann, M. (Amsterdam : Elsevier B.V., 2019)
    Over the recent years, several studies have pointed out the impact of manufacturing on the environment. Especially machining offers great potential for the conservation of energy, resources and the reuse of raw materials. ...
  • Denkena, Berend; Dahlmann, Dominik; Floeter, F.; Bruehne, T. (Amsterdam : Elsevier B.V., 2014)
    Difficult-to-machine materials are still challenging the production industry. Examples are highly complex components of aircraft engines. Alongside innovative processes, also improved machine tool components are helping ...
  • Denkena, Berend; Dittrich, Marc-André; Jacob, Stefan (Amsterdam : Elsevier, 2016)
    High production costs and material removal rates characterize the manufacturing of aircraft components made of titanium. Due to competitive pressure, the manufacturing processes are highly optimized from an economical ...
  • Denkena, Berend; Bergmann, Benjamin; Rahner, Björn-Holger (Amsterdam : Elsevier B.V., 2018)
    Fibre-reinforced plastics (FRPs) are becoming increasingly important in aerospace and automotive applications. However, dry machining of FRPs generates abrasive and electrically conductive dust particles that can furthermore ...
  • Denkena, Berend; Brühne, Tilmann (Amsterdam : Elsevier B.V., 2016)
    Difficult-to-machine materials are still challenging the production industry. Examples are highly complex components of aircraft engines. Alongside innovative processes, also improved machine tool components are helping ...
  • Denkena, Berend; Litwinski, K.; Schönherr, M. (Amsterdam : Elsevier, 2013)
    In this paper an innovative drive concept for robots to improve their machining capability is presented. As a test bed a two-axis robot is designed and equipped with torque motors with load-sided high resolution encoders ...
  • Böß, Volker; Denkena, Berend; Henning, S. (Amsterdam : Elsevier, 2015)
    In this paper, a novel approach for cutting simulation of skive hobbing is presented. Skive hobbing is a process applied for finishing of already hardened gears. The process is characterized by varying tool engagements and ...
  • Denkena, Berend; Grove, Thilo; Schmidt, Carsten (Amsterdam : Elsevier B.V., 2018)
    In combustion engines a large percentage of mechanical losses result from friction, for example within the cylinder liner. In order to reduce the friction between cylinder liner and piston, micro dimples in the surface ...
  • Brüning, Jan; Denkena, Berend; Dittrich, Marc-André; Park, Hong-Seok (Amsterdam : Elsevier B.V., 2016)
    Today, especially machining of large, integral constructed structural parts requires expensive machining centers. In contrast, modern industrial robots are characterized by flexible applications, large working spaces and ...
  • Beblein, S.; Breidenstein, Bernd; Denkena, Berend; Pusch, C.; Hoche, H.; Oechsner, M. (Amsterdam : Elsevier BV, 2017)
    The conventional development of a coating system for cutting tools includes a variety of test series with elaborate experimental parameter studies. In particular, experimental investigations of the cutting behavior cause ...
