Análisis numérico y experimental del rectificado de caras orientado al comportamiento térmico del proceso
Urgoiti Elorriaga, Lander (2020-10-22)El rectificado es un proceso de mecanizado por abrasión el cual suele estar situado al final del proceso deproducción de las piezas. Esto quiere decir que el valor de las piezas al llegar al punto de necesitar serrectificadas ... -
Detailed Thermo-Kinematic Analysis of Face Grinding Operations with Straight Wheels
Urgoiti, Lander; Barrenetxea Azpeitia, David; Sánchez Galíndez, José Antonio ; Lanzagorta, José Luis (MDPI, 2020-04-18)This paper presents a new model that relates thermal aspects with process kinematics in face grinding applications with straight wheels. Changes in chip thickness along the contact area were considered in the model, which ... -
Friction improvement via grinding wheel texturing by dressing
García Moreno, María; Álvarez Ruiz, Jorge; Barrenetxea Azpeitia, David; Marquínez González, José Ignacio; Godino Fernández, Leire (Springer, 2020-05-20)The economic and environmental cost of friction in machinery and transport is significantly remarkable, the machine tool being one of the most affected. In this sector, the movements are fully affected by the friction ... -
Implicit Subspace Iteration to Improve the Stability Analysis in Grinding Processes
Álvarez Ruiz, Jorge; Zatarain, Mikel; Barrenetxea Azpeitia, David; Marquínez, Jose Ignacio; Izquierdo Aramburu, Borja (MDPI, 2020-11-19)An alternative method is devised for calculating dynamic stability maps in cylindrical and centerless infeed grinding processes. The method is based on the application of the Floquet theorem by repeated time integrations. ... -
Improvement of Shape Error for Slender Parts in Cylindrical Traverse Grinding by Part-Deformation Modelling and Compensation
Méndez Sánchez, Iván; Álvarez Ruiz, Jorge; Barrenetxea Azpeitia, David; Godino Fernández, Leire (MDPI, 2021-12-09)Achieving geometrical accuracy in cylindrical traverse grinding for high-aspect slender parts is still a challenge due to the flexibility of the workpiece and, therefore, the resulting shape error. This causes a bottleneck ... -
On the Influence of Infra-Red Sensor in the Accurate Estimation of Grinding Temperatures
Urgoiti, Lander; Barrenetxea Azpeitia, David; Sánchez Galíndez, José Antonio ; Pombo Rodilla, Iñigo; Álvarez, Jorge (MDPI, 2018-11-26)Workpiece rejection originated by thermal damage is of great concern in high added-value industries, such as automotive or aerospace. Surface temperature control is vital to avoid this kind of damage. Difficulties in ...
