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 ...
A Note on Interpreting Tool Temperature Measurements from Thermography

Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Taylor & Francis, 2015)

Thermography (thermal imaging) is a well-established experimental method for studying cutting tool temperature distributions. In one form, cutting edge temperatures within the chip / tool contact area are deduced from ...
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 ...
