Identification of the Parameter Values of the Constitutive and Friction Models in Machining Using EGO Algorithm: Application to Ti6Al4V
ARRAZOLA, PEDRO JOSE (MDPI, 2022)The application of artificial intelligence and increasing high-speed computational performance is still not fully explored in the field of numerical modeling and simulation of machining processes. The efficiency of the ... -
Influence of Coulomb’s Friction Coefficient in Finite Element Modeling of Orthogonal Cutting of Ti6Al4V
ARRAZOLA, PEDRO JOSE (Trans Tech Publications, 2022)The reliability of the pertinent parameters set of Johnson-Cook constitutive model is highly linked with the friction condition at the tool-chip-workpiece interface. In the present work, a study on the influence of Coulomb’s ... -
Inverse Identification of the Ductile Failure Law for Ti6Al4V Based on Orthogonal Cutting Experimental Outcomes
Sela, Andrés; Soler Mallol, Daniel; Ortiz-de-Zarate, Gorka; ARRAZOLA, PEDRO JOSE (MDPI, 2021)Despite the prevalence of machining, tools and cutting conditions are often chosen based on empirical databases, which are hard to be made, and they are only valid in the range of conditions tested to develop it. Predictive ... -
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 ... -
A Systematic Method for Assessing the Machine Performance of Material Extrusion Printers
Nieto Fuentes, Endika; ARRAZOLA, PEDRO JOSE (MDPI, 2024)The performance assessment of additive manufacturing (AM) printers is still a challenge since no dedicated standard exists. This paper proposes a systematic method for evaluating the dimensional and geometrical performance ... -
Tool wear for finishing milling of green thermoplastic-ceramic composites fabricated with pellet AM
Aldeiturriaga Olabarri, Naiara; ARRAZOLA, PEDRO JOSE (Elsevier, 2024)The wear of milling tools used for finishing green ceramics shaped by pellet additive manufacturing can be challenging. This article aims to evaluate the tool life of a tool, initially dedicated to thermoplastics, when ...
