    An active aerodynamic feeding system developed at the IFA offers a large potential regarding output rate, reliability and neutrality towards part geometries. In this paper, the procedure of a genetic algorithm's into the ...
  • Krebs, Daniel; Borchert, Gunnar; Raatz, Annika (Amsterdam : Elsevier B.V., 2016)
    The article focuses on methods for designing modular cable-driven orientation mechanisms that can be attached to robot systems that lack on rotational degrees of freedom. The approach yields assembly systems for high speed ...
  • Grzesik, W.; Denkena, Berend; Żak, K.; Grove, Thilo; Bergmann, Benjamin (London : Springer, 2016)
    In this paper, the contribution of tool wear to the energy balance was determined for precision hard turning using chamfered CBN cutting tools. The tool nose wear VBC and the corresponding changes of component forces Fc, ...
  • Ahrens, M.; Fischer, R.; Dagen, M.; Denkena, Berend; Ortmaier, T. (Amsterdam : Elsevier, 2013)
    Using conventional grinding wheels, wheel-sided chatter vibration is one of the limiting factors in terms of productivity and surface finish. Initial vibration related to the dynamic behavior of the machine tool copy on ...
  • Belski, A.; Taptimthong, P.; Wurz, M.C.; Rissing, L. (Les Ulis : EDP Sciences, 2013)
    A magnetic field is generated by feeding electric current to micro coils. The higher the current, the higher the magnetic field is. A main disadvantage of coils in micro systems is the limited thermal resistance and as a ...
  • Adamczuk, R.R.; Seume, Jörg R. (Amsterdam : Elsevier, 2013)
    The jet engine maintenance process is complex, expensive and time-consuming. It often requires engine disassembly or boroscopic examinations. In order to accelerate the process and reduce the down time of an engine we ...
  • Denkena, Berend; Köhler, J.; Stieghorst, J.; Turger, A.; Seitz, J.; Fau, D.R.; Wolters, L.; Angrisani, N.; Reifenrath, J.; Helmecke, P. (Amsterdam : Elsevier, 2013)
    In this paper the performance of a magnesium based implant system is analyzed. A special emphasis is placed on the impact of stress on the corrosion behavior of the magnesium alloy. An implant system containing a plate and ...
  • Denkena, Berend; Köhler, J.; Turger, A.; Helmecke, P.; Correa, T.; Hurschler, C. (Amsterdam : Elsevier, 2013)
    To date, bioceramics have not been applied successfully in total knee joint endoprostheses. Sintered bioceramics can be machined only by grinding and polishing processes. Due to high quality requirements, there are significant ...
  • 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 ...
  • Denkena, Berend; Nemeti, Andrea (Amsterdam : Elsevier, 2013)
    Tool and mould manufacturers typically prepare their quotation provide an accurate price of, for example, a die casting mould is a key competitive factor for such companies. However, particularly in the customised production ...
  • Denkena, Berend; Schmidt, A.; Henjes, J.; Niederwestberg, D.; Niebuhr, C. (Amsterdam : Elsevier, 2013)
    This paper presents a method for a NC-Simulation based prediction of shape errors caused by thermal expansions in machining of complex workpieces. In the first part of the paper the basic approach of modeling a thermomechanical ...
  • Denkena, Berend; Gümmer, O. (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; Koeller, M. (Amsterdam : Elsevier, 2013)
    Process monitoring can prevent machine and tool failure in metal-cutting. A successful process monitoring of cutting processes depends on reliable monitoring limits for the process. In industrial applications these limits ...
