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 ... -
Enhancing surface integrity of A7050-T7451 aluminium alloy by pneumatic machine hammer peening
Madariaga, Aitor; CUESTA ZABALAJAUREGUI, MIKEL; Dominguez Romero, Erika; Garay, Ainara; Ortiz-de-Zarate, Gorka; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2022)Aerostructures withstand cyclic mechanical loads and therefore, their design must fulfil surface integrity and fatigue strength requirements. This paper studies the effect of pneumatic machine hammer peening on surface ... -
Evaluation of different flow stress laws coupled with a physical based ductile failure criterion for the modelling of the chip formation process of Ti-6Al-4V under broaching conditions
Ortiz-de-Zarate, Gorka; Saez de Buruaga, Mikel; Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Elsevier, 2019)During the machining of Ti-6Al-4V the changing deformation mechanisms produce a complex microstructure of segmented chips, which directly influenced tool-wear and process stability. Numerical simulation could give an insight ... -
Force Prediction Methodology for Complex Shape Broaching
Ortiz-de-Zarate, Gorka; Soler Mallol, Daniel; Soriano Moreno, Denis; Madariaga, Aitor; Etxebeste , Mikel; ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2023)Broaching is widely used for the manufacturing of complex geometries which requires high dimensional accuracy and surface finishing (e.g., fir tree, dovetail). A software development for force prediction in complex shape ...
