Influence of Microstructure on Chip Formation when Broaching Ferritic-Pearlitic Steels 

Arrieta Galdós, Iñaki Mirena; ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2017)
Broaching is a specific process characterized by relatively low cutting speeds and uncut chip thicknesses. The latter is in the range of 0.1 to 0.25 mm in the roughing section of the tool but can decrease down to 0.0015 ...

Simulation of distortion due to machining of thin-walled components 

ARRAZOLA, PEDRO JOSE (Elsevier, 2013)
The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ...

Numerical Simulation of Surface Modification During Machining of Nickel-based Superalloy 

ARRAZOLA, PEDRO JOSE; Imaz Ciaran, Mikel; Rotella, Giovanna (Elsevier, 2015)
The main objective of this study is to implement a reliable FE model of the orthogonal machining of a Nickel based superalloy for the prediction of microstructural changes occurring during the process. A FE numerical model ...

Experimental analysis of cutting force reduction during ultrasonic assisted turning of Ti6Al4V 

ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2019)
The machining of difficult-to-cut materials involves limitations leading to low productivity in conventional machining processes due to high cutting forces and tool wear rates. The ultrasonic ...

Multi revolution finite element model to predict machining induced residual stresses in Inconel 718 

Kortabarria Lezeta, Aitor; ARRAZOLA, PEDRO JOSE (Elsevier, 2013)
Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ...

A sensibility analysis to geometric and cutting conditions using the particle finite element method (PFEM) 

ARRAZOLA, PEDRO JOSE; Kortabarria Lezeta, Aitor (Elsevier, 2013)
The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal ...

An optimization methodology for material databases to improve cutting force predictions when milling martensitic stainless steel JETHETE-M152 

Aristimuño, Patxi Xabier; Basagoiti Astigarraga, Rosa; ARRAZOLA, PEDRO JOSE; Lazcano Rayo, Xabier; Sela Barrial, Andres (Elsevier Ltd., 2018)
A material database for JETHETE-M152 was developed applying a novel methodology for improving the precision of cutting forces. This approach defines a variable specific edge force depending on the feed rate and cutting ...

Microstructure based flow stress model to predict machinability in ferrite–pearlite steels 

Saez de Buruaga, Mikel; Aristimuño, Patxi Xabier; Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2019)
A new flow stress model is proposed to describe the behaviour of ferrite–pearlite steels based on microstructure properties, including the effect of high strains, strain rates and temperatures. The model introduces strain ...

Effect of heat Treatment Conditions on the Machinability of Ti64 and Ti54 M Alloys 

Garay, Ainara; Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Elsevier, 2012)
Orthogonal tests on cylindrical workpieces were carried out to analyze the effect of heat treatment on the machinability of newly developed Ti54M titanium alloy in comparison with Ti64. This paper focuses on the comparison ...

Machining behaviour of Ti-6Al-4V and Ti-5553 alloys in interrupted cutting with PVD coated cemented carbide 

Garay, Ainara; ARRAZOLA, PEDRO JOSE (Elsevier, 2012)
Machining behaviour of Ti-5553, Ti-6Al-4 V mill-annealed (MA) and Ti-6Al-4 V solution treated and aged (STA) alloys was studied in different interrupted cutting operations using PVD coated cemented carbide tools. Single ...
