  • A comparative analysis of ceramic and cemented carbide end mills 
    Dröder, Klaus; Karpuschewski, Bernhard; Uhlmann, Eckart; Arrabiyeh, Peter A.; Berger, Daniel; Busemann, Sarah; Hartig, Jörg; Madanchi, Nadine; Mahlfeld, Georg; Sommerfeld, Christian (Berlin : Springer, 2020)
    Milling of ferrous metals is usually performed by applying cemented carbide tools due to their high hardness, temperature and wear resistance. Recently, ceramic tool materials have been on the rise and enhanced the efficiency ...
  • A study of grease lubricants under wind turbine pitch bearing conditions 
    Schwack, Fabian; Bader, Norbert; Leckner, Johan; Demaille, Claire; Poll, Gerhard (Amsterdam [u.a.] : Elsevier Science, 2020)
    Pitch bearings in wind turbines are affected by reciprocating motion due to pitch control. The combination of oscillating operation, high loads, and mixed lubrication often leads to wear. Grease lubricants in wind turbine ...
  • Effect of load reduction mechanisms on loads and blade bearing movements of wind turbines 
    Stammler, Matthias; Thomas, Philipp; Reuter, Andreas; Schwack, Fabian; Poll, Gerhard (Chichester : John Wiley and Sons Ltd, 2019)
    The power control of wind turbines is usually realized via a change in the pitch angle of the rotor blades. Pitching facilitates the exact control of the turbines and the reliable deceleration of the rotor when required. ...
  • Energy consumption characterization in precision hard machining using CBN cutting tools 
    Grzesik, Wit; Denkena, Berend; Żak, Krzysztof; 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, ...
  • Estimation of Dynamic Grinding Wheel Wear in Plunge Grinding 
    Ahrens, M.; Damm, J.; Dagen, M.; Denkena, Berend; Ortmaier, T. (Amsterdam : Elsevier BV, 2017)
    Using conventional grinding wheels, self-excited vibrations are one of the most limiting factors in terms of productivity and process stability in cylindrical plunge grinding. Depending on the dynamic behavior of the ...
  • Influence of cemented carbide composition on cutting temperatures and corresponding hot hardnesses 
    Vornberger, Anne; Picker, Tobias; Pötschke, Johannes; Herrmann, Mathias; Denkena, Berend; Krödel, Alexander; Michaelis, Alexander (Basel : MDPI AG, 2020)
    During metal cutting, high temperatures of several hundred-degree Celsius occur locally at the cutting edge, which greatly impacts tool wear and life. Not only the cutting parameters, but also the tool material’s properties ...
  • Material removal and chip formation mechanisms of UHC-steel during grinding 
    Denkena, Berend; Grove, Thilo; Göttsching, Tim (London : Springer, 2017)
    The grinding process is still an important manufacturing process for the machining of automotive components. For power train components, ultra-high carbon steel (UHC-steel) is a promising new innovative alloy because of ...
  • Microstructure and wear behaviour of high alloyed hot-work tool steels 1.2343 and 1.2367 under thermo-mechanical loading 
    Malik, I.Y.; Lorenz, U.; Chugreev, A.; Behrens, B.-A. (Bristol : Institute of Physics Publishing, 2019)
    Tools and their maintenance costs in hot forging processes account for a considerable proportion of the total components' costs. Forging tools undergo extreme heating and subsequent cooling during the forging process and ...
  • A New Tool Concept for Milling Automotive Components 
    Denkena, Berend; Grove, Thilo; Krödel, Alexander (Amsterdam : Elsevier, 2016)
    Due to the rising number of car variants, the production systems in automobile industry are driven by a strong demand for flexible production processes. In the production of thin-walled workpieces, forming and cutting ...
  • Optimization of the tribological performance of rectangular seals in automotive transmissions 
    Gronitzki, M.; Poll, G.W.G. (London : SAGE Publications Ltd., 2007)
    Rectangular seals - a special type of face seals - are currently used in rotating connections of automatic automotive transmissions (double clutch transmissions, continuously variable transmissions, and 6-automated ...
  • Selective oxidation of tool steel surfaces under a protective gas atmosphere using inductive heat treatment 
    Schöler, S.; Yilkiran, D.; Wulff, D.; Özkaya, F.; Möhwald, K.; Behrens, Bernd-Arno; Maier, H.J. (Les Ulis : EDP Sciences, 2018)

  • Tools and Strategies for Grinding of Riblets on Freeformed Compressor Blades 
    Denkena, Berend; Grove, Thilo; Krawczyk, T. (Amsterdam : Elsevier BV, 2016)
    A major goal in the design of turbomachinery is the increase of efficiency. To attain this increase, the flow losses must be reduced. A substantial proportion of the losses is generated by skin friction between compressor ...
  • Wear curve based online feature assessment for tool condition monitoring 
    Denkena, Berend; Bergmann, Benjamin; Stiehl, Tobias H. (Amsterdam : Elsevier B.V., 2020)
