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 ... -
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 ... -
Effect of Tool Geometry and LCO2 Cooling on Cutting Forces and Delamination when Drilling CFRP Composites Using PCD Tools
Rodríguez Bogajo, Iñigo; Soriano Moreno, Denis; Ortiz-de-Zarate, Gorka; CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (Elsevier, 2022)Lightweight materials like Carbon Fiber Reinforced Polymers (CFRPs) present certain challenges, mainly regarding the resultant surface integrity of the holes. Different techniques such as optimized tool geometries, machining ... -
Experimental evaluation and surface integrity analysis of cryogenic coolants approaches in the cylindrical plunge grinding
Abedrabbo Hazbun, Anibal Faruk; Soriano Moreno, Denis; Madariaga, Aitor; Fernandez Manchado, Raul; ARRAZOLA, PEDRO JOSE (Nature Publishing Group, 2021)Replacement of pollutant fuids with eco-friendly strategies in machining operations signifcantly contributes to protecting the environment, diminishing global warming, and ensuring a healthier workplace for employees. This ... -
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. The ... -
Surface drag analysis after Ti-6Al-4V orthogonal cutting using grid distortion
Sela, Andrés; Ortiz-de-Zarate, Gorka; Soler Mallol, Daniel; Aristimuño, Patxi Xabier; Soriano Moreno, Denis; ARRAZOLA, PEDRO JOSE (Elsevier Ltd, 2020)Surface integrity directly affects the mechanical behavior of the workpiece, which is especially relevant on fatigue behavior. To characterize the quality of the machined surface, aspects such as material damage, roughness ... -
Tool Geometry Optimisation for LCO2 Assisted Milling of Ti6Al4V
rodriguez, Iñigo; Soriano Moreno, Denis; CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (Elsevier, 2024)Titanium alloy Ti6Al4V is of great importance to the aeronautical and medical sectors due to its mechanical properties such as a high strength-to-weight ratio and corrosion resistance. On the downside, machining Ti6Al4V ...
