    • Mechanical properties of 3D-printing polylactic acid parts subjected to bending stress and fatigue testing 

      Travieso Rodríguez, José Antonio; Jerez Mesa, Ramón; Llumà Fuentes, Jordi; Traver Ramos, Oriol; Gómez Gras, Giovanni; Roa Rovira, Joan Josep (Multidisciplinary Digital Publishing Institute (MDPI), 2019-11-22)
      Article
      Accés obert
      This paper aims to analyse the mechanical properties response of polylactic acid (PLA) parts manufactured through fused filament fabrication. The influence of six manufacturing factors (layer height, filament width, fill ...

    • Mechanical strengthening in S235JR steel sheets through vibration-assisted ball burnishing 

      Llumà Fuentes, Jordi; Gómez Gras, Giovanni; Jerez Mesa, Ramón; Rue Mascarell, Jaume; Travieso Rodríguez, José Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2020-07-28)
      Article
      Accés obert
      The superficial effect of hardening caused after vibration-assisted ball burnishing and its consequences in the tensile behavior of a carbon steel material are studied in this paper. As ball burnishing affects the material ...

    • Spectral analysis of forces during a ball-burnishing process assisted by vibrations 

      Gómez Gras, Giovanni; Travieso Rodríguez, José Antonio; Llumà Fuentes, Jordi; Jerez Mesa, Ramón (Destech, 2015)
      Text en actes de congrés
      Accés obert
      One of the most recent innovations in manufacturing engineering has been the assistance of machining, finishing and superfinishing processes with vibrations as a means of improving the mechanical properties of the workpieces. ...

    • Study of a ball-burnishing vibration-assisted process 

      Gómez Gras, Giovanni; Travieso Rodríguez, José Antonio; González Rojas, Hernán Alberto; Nápoles Alberro, Amelia; Carrillo, Francisco Javier; Dessein, Gilles (2015-01-01)
      Article
      Accés obert
      First of all, this work refers to the study of the ball-burnishing process assisted by a vibration. It starts by considering that this vibration helps to make the development of this finishing process easier, because it ...

    • Study of the lateral pass width for conventional and ultrasonic vibrations-assisted ball burnishing on Ti-6Al-4V specimens 

      Jerez Mesa, Ramón; Gómez Gras, Giovanni; Llumà Fuentes, Jordi; Travieso Rodríguez, José Antonio (2016)
      Text en actes de congrés
      Accés obert
      Ball burnishing is a technological finishing process based on plastic deformation of the objective surface by means of a hard ball gliding over it. Along with its easiness of application, possible on the same machine where ...

    • Surface roughness assessment after different strategy patterns of ultrasonic ball burnishing 

      Jerez Mesa, Ramón; Gómez Gras, Giovanni; Travieso Rodríguez, José Antonio (2017-10-05)
      Article
      Accés obert
      Ball burnishing is a comprehensive finishing process consisting on deforming plastically a certain surface by the action of a rolling sphere-shaped indenter. In this work, an AISI 1038 workpiece is burnished in two phases. ...
