  • Influence of the cutting tool compliance on the workpiece surface shape in face milling of workpiece compounds 
    Denkena, Berend; Hasselberg, E. (Amsterdam : Elsevier, 2015)
    A currently common method to design high-performance workpieces is to combine two or more materials to one compound. In this way, workpieces can be composed of the most qualified materials according to local loads. When ...
  • Inverse determination of constitutive equations and cutting force modelling for complex tools using oxley's predictive machining theory 
    Denkena, Berend; Grove, Thilo; Dittrich, Marc-André; Niederwestberg, D.; Lahres, M. (Amsterdam : Elsevier, 2015)
