    Breidenstein, Bernd; Denkena, Berend; Mörke, Tobias; Hockauf, R. (Amsterdam : Elsevier, 2015)
    Focusing on the impact of machining on structural integrity and fatigue life of components the surface and subsurface properties are of major importance. It is well known that machining induced residual stresses have a ...
  • Increased performance in high speed turning of Inconel 718 by laser structuring of PcBN tools 
    Denkena, Berend; Grove, Thilo; Krödel, Alexander; Ellersiek, Lars (Amsterdam : Elsevier B.V., 2018)
    In order to improve the cutting performance of PcBN tools, the cutting edge is prepared e.g. by grinding or brushing. Since PcBN is the second hardest material besides diamond, mechanical preparation of PcBN tools is ...
  • The influence of deep rolling on the surface integrity of AISI 1060 high carbon steel 
    Abrão, A.M.; Denkena, Berend; Köhler, Jens; Breidenstein, Bernd; Mörke, Tobias (Amsterdam : Elsevier, 2014)
    The aim of this work is to study the influence of selected deep rolling parameters (rolling pressure and number of passes) on the surface integrity of fully annealed AISI 1060 high carbon steel. In addition to the mechanical ...
  • Influence of Hard Turned Roller Bearings Surface on Surface Integrity after Deep Rolling 
    Denkena, B.; Grove, T.; Maiss, O. (Amsterdam [u.a.] : Elsevier, 2016)
    The endurance of highly loaded parts such as bearings is influenced by their surface integrity. Low surface roughness and high compressive residual stresses lead to an increased lifetime. In contrast to grinding and honing, ...
  • Influence of XHV-adequate atmosphere on surface integrity 
    Prasanthan, V.; Denkena, B.; Bergmann, B. (Berlin, Heidelberg : Springer, 2022)
    In aerospace engineering, high temperature alloys such as titanium are the preferred choice. However, machining of such materials remains a major challenge due to high process forces and process temperatures. Currently, ...

    Santos, Filipe Figueiredo dos; Silva, Sandro da Costa; Abrão, Alexandre Mendes; Denkena, Berend; Breidenstein, Bernd; Meyer, Kolja (Rio de Janeiro : Universidade Federal do Rio de Janeiro, 2020)
    Surface integrity refers to a set of characteristics of the surface and subsurface layer that have great influence on the functional performance of mechanical components under conditions of wear, corrosion and fatigue, and ...
  • Kinematic and stochastic surface topography of machined tial6v4-parts by means of ball nose end milling 
    Denkena, Berend; Böß, Volker; Nespor, D.; Samp, A. (Amsterdam : Elsevier BV, 2011)
    Ball nose end mills are usually applied during 5-axes machining of high functional parts especially in the aerospace industry. The systematical study of the relationship between process forces and kinematics, surface ...
  • Prediction of the Principal Stress Direction for 5-axis Ball End Milling 
    Böß, Volker; Grove, Thilo; Denkena, Berend; Mücke, A.; Nespor, D. (Amsterdam : Elsevier, 2016)
    While regenerating damaged components, e.g. compressor blades, the removal of excess weld material called re-contouring often determines the surface integrity including the residual stress state. A load-specific residual ...
  • Residual stresses in milled titanium parts
