Effect of cutting speed on the surface integrity of face milled 7050-T7451 aluminium workpieces 

Pérez Guisado, Ion; Madariaga, Aitor; ARRAZOLA, PEDRO JOSE; CUESTA ZABALAJAUREGUI, MIKEL; Garay, Ainara (Elsevier Ltd., 2018)
The guarantee of surface integrity has become a primary objective for researchers when analysing the reliability of machined aircraft aluminium alloy structural parts in high-speed machining. This work studies the effect ...

Experimental and FEM analysis of surface integrity when broaching Ti64 

Ortiz-de-Zarate, Gorka; Madariaga, Aitor; Garay, Ainara; Azpitarte-Aranzabal, Larraitz; CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (Elsevier, 2018)
The performance of aeronautic critical components is strongly dependent on its fatigue behavior, which is directly linked to their surface integrity condition. Broaching operation is a machining operation extensively used ...

Hole quality improvement in CFRP/Ti6Al4V stacks using optimised flow rates for LCO2 and MQL sustainable cooling/lubrication 

rodriguez, Iñigo; ARRAZOLA, PEDRO JOSE; CUESTA ZABALAJAUREGUI, MIKEL (Elsevier, 2024)
Carbon fibre reinforced polymer/titanium stacks (CFRP/Ti6Al4V) are employed in aeronautics due to their excellent weight-to-strength ratio and corrosion properties. However, these same material properties present challenges ...

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 ...

Prediction of Surface Roughness of SLM Built Parts after Finishing Processes Using an Artificial Neural Network 

Soler Mallol, Daniel; Telleria, Martin; CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (MDPI, 2022)
A known problem of additive manufactured parts is their poor surface quality, which influences product performance. There are different surface treatments to improve surface quality: blasting is commonly employed to improve ...

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 ...

Surface roughness assessment on hole drilled through the identification and clustering of relevant external and internal signal statistical features 

Duo, Aitor; Basagoiti, Rosa; ARRAZOLA, PEDRO JOSE; CUESTA ZABALAJAUREGUI, MIKEL; Illarramendi, Miren (Elsevier, 2022)
Drilling is a continuous cutting process where two or more cutting edges remove the material, to obtain the desired feature. During the chip evacuation, it generally rubs against the generated surface. Thus, the roughness ...

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 Post-Processing Treatment on Fatigue Performance of Ti6Al4V Alloy Manufactured by Laser Powder Bed Fusion 

CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (MDPI, 2023)
Fatigue properties of parts are of particular concern for safety-critical structures. It is well-known that discontinuities in shape or non-uniformities in materials are frequently a potential nucleus of fatigue failure. ...
