An analytical approach to calculate stress concentration factors of machined surfaces
Perez Guisado, Ion; ARRAZOLA, PEDRO JOSE; Madariaga, Aitor; CUESTA ZABALAJAUREGUI, MIKEL; Soriano Moreno, Denis (Elsevier Ltd., 2021)Machining operations affect the properties of the final surface layer, and these can impact on its functional per- formance, particularly on fatigue behaviour. Among the properties of the machined surface, surface topography ... -
Combining experimental and FEM approaches to determine the influence of workpiece temperature on fundamental variables in the machining process
Ortiz-de-Zarate, Gorka; ARRIETA, Iñaki Mirena; Soriano Moreno, Denis; Oruna Tena, Ainara; Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Materials Research Forum LLC, 2024)In machining it is common practice to use lubricants to enhance machinability, resulting in improved part quality and reduced tool wear. However, emerging efforts are centered on mitigating the environmental impact of ... -
Correcting distortions of thin-walled machined parts by machine hammer peening
CUESTA ZABALAJAUREGUI, MIKEL; Ortiz-de-Zarate, Gorka; Sáenz de Argandoña, Eneko; Soriano Moreno, Denis; ARRAZOLA, PEDRO JOSE (Elsevier, 2023)Thin-walled aerostructural components frequently get distorted after the machining process. Reworking to correct distortions or eventually rejecting parts significantly increases the cost. This paper proposes a new approach ... -

Influence of cryogenic grinding surface on fatigue performance of carburised 27MnCr5
Abedrabbo Hazbun, Anibal Faruk; Madariaga, Aitor; Soriano Moreno, Denis; Fernandez Manchado, Raul; ARRAZOLA, PEDRO JOSE (Elsevier, 2023)Automotive transmission components are subjected to cyclic loads and, thus, must have a reliable fatigue performance. Since fatigue cracks nucleate at the surface, it is necessary to guarantee that its surface integrity ... -
A mechanistic model to predict cutting force on orthogonal machining of Aluminum 7475-T7351 considering the edge radius
Ortiz-de-Zarate, Gorka; ARRIETA, Iñaki Mirena; Soriano Moreno, Denis; Aristimuño, Patxi Xabier; Medina-Clavijo, Bentejui; ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2019)The ploughing force related with action of edge radius is an important factor which influences flow stress, chip formation or surface integrity. Some fraction of the cutting forces are called parasitic (additional) forces ... -
Sensitivity Analysis of Various Geometries of PCD and Cemented Tungsten Carbide Cutting Tools during the Milling of GFRP Composite
Soriano Moreno, Denis; CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (MDPI, 2022)Although much research has been carried out in the field of the milling of GFRP (Glass Fibre Reinforced Polymer) composites, the complexity of the process is such that it is still not mastered in many industrial cases.
