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 ...

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 ...

Experimental and FEM analysis of surface integrity when broaching Ti64 

Ortiz-de-Zarate, Gorka; Madariaga, Aitor; Garay, Ainara; Azpitarte Aranzabal, Larraitz; CUESTA ZABALAJAUREGI, 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 ...

A mechanistic model to predict cutting force on orthogonal machining of Aluminum 7475-T7351 considering the edge radius 

Ortiz-de-Zarate, Gorka; Arrieta Galdós, Iñaki Mirena; Soriano, 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 the input parameters of a physical based ductile failure model of Ti-6Al-4V for the prediction of surface integrity 

Ortiz-de-Zarate, Gorka; Sela, Andrés; Madariaga, Aitor; ARRAZOLA, PEDRO JOSE (Elsevier Ltd, 2020)
In machining of Ti-6Al-4V, it is commonly reported the appearance of segmented chip produced by adiabatic shearing (at high cutting speeds) and lack of ductility (at low cutting speeds). Moreover, machining is a manufacturing ...

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, 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 ...

In-SEM micro-machining reveals the origins of the size effect in the cutting energy 

Ortiz-de-Zarate, Gorka; Sela Barrial, Andres; Arrieta Galdós, Iñaki Mirena; ARRAZOLA, PEDRO JOSE (Springer Nature, 2021)
High-precision metal cutting is increasingly relevant in advanced applications. Such precision normally requires a cutting feed in the micron or even sub-micron dimension scale, which raises questions about applicability ...

Measurement of plastic strain and plastic strain rate during orthogonal cutting for Ti-6Al-4V 

Sela Barrial, Andres; Ortiz-de-Zarate, Gorka; Soler Mallol, Daniel; Aristimuño, Patxi Xabier; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2021)
Finite Element Modelling used to predict machining outcomes needs to be supplied with the appropriate material thermomechanical properties which are obtained by specific testing devices and methodologies. However, these ...

A novel methodology to characterize tool-chip contact in metal cutting using partially restricted contact length tools 

Ortiz-de-Zarate, Gorka; Madariaga, Aitor; ARRAZOLA, PEDRO JOSE (2021)
A novel methodology to map the friction and normal stress distribution on the rake face using Partially Restricted Contact Length Tools in orthogonal cutting tests is proposed. The influence of cutting speed, feed and ...

Surface topography irregularities generated by broaching 

Ortiz-de-Zarate, Gorka; Madariaga, Aitor; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2022)
Surface topography irregularities generated by broaching are analysed. Experimental tests were carried out on three workpiece materials: AISI 1045, Ti-6Al-4V, and Inconel 718, varying the cutting speed, rise per tooth, and ...
