    Peña Pitarch, Esteve; Ticó Falguera, Neus; Al Omar Mesnaoui, Anas; Alcelay Larrión, José Ignacio (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The aim of this work is to show a novel environment to simulate and calculate the forces exerted in each point of contact when grasping with power or precision. Virtual hand was designed and validated with 25 degrees of ...
  • Analysis of roughness, force and vibration signals in ball-end milling processes 

    Álvarez Flórez, Jesús Andrés; Buj Corral, Irene; Vivancos Calvet, Joan (2015)
    Text en actes de congrés
    Accés obert
    In the present paper, roughness, force and vibration signals from ball-end milling processes are analysed. From the roughness signal actual feed value was obtained as expected. From the force and vibration signals both the ...
  • Spectral analysis of forces during a ball-burnishing process assisted by vibrations 

    Gómez Gras, David; Travieso Rodriguez, Jose 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. ...
