    • A comparative study of residual stress profiles on Inconel 718 induced by dry face turning 

      Kortabarria, Aitor; Madariaga, Aitor; Fernandez, Eduardo; Esnaola, Jon Ander; ARRAZOLA, PEDRO JOSE (Elsevier, 2011)
      Residual stress profiles induced by different dry face turning conditions are compared employing X-ray diffraction method, Hole-Drilling method and Finite Element Modelling. It is well known that the surface integrity ...

    • Effect of innovative finishing operations on the tribological performance of steel 27MnCr5 

      Madariaga, Aitor; Abedrabbo Hazbun, Anibal Faruk; Soriano Moreno, Denis; Alpizar Fernandez, Raul; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2022)
      Transmission shafts used in the automotive sector must have a good tribological performance, and therefore an enhanced surface integrity. This paper aims to study the effect of eco-friendly innovative finishing operations ...

    • Enhancing surface integrity of A7050-T7451 aluminium alloy by pneumatic machine hammer peening 

      Madariaga, Aitor; CUESTA ZABALAJAUREGUI, MIKEL; Dominguez Romero, Erika; Garay, Ainara; Ortiz-de-Zarate, Gorka; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2022)
      Aerostructures withstand cyclic mechanical loads and therefore, their design must fulfil surface integrity and fatigue strength requirements. This paper studies the effect of pneumatic machine hammer peening on surface ...

    • Force Prediction Methodology for Complex Shape Broaching 

      Ortiz-de-Zarate, Gorka; Soler Mallol, Daniel; Soriano Moreno, Denis; Madariaga, Aitor; Etxebeste , Mikel; ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2023)
      Broaching is widely used for the manufacturing of complex geometries which requires high dimensional accuracy and surface finishing (e.g., fir tree, dovetail). A software development for force prediction in complex shape ...

    • Influence of tool wear on residual stresses when turning Inconel 718 

      Madariaga, Aitor; Kortabarria, Aitor; Hormaetxe Fernández, Exabier; Garay, Ainara; ARRAZOLA, PEDRO JOSE (Elsevier, 2016)
      This paper analyzes the effect of tool wear on residual stresses when turning. Inconel 718 discs were machined for prolonged periods at several cutting speeds, feed-rates and depth of cut. Tests were interrupted to measure ...
