Modeling of cutting force and final thickness for low stiffness 2024-T3 aluminum alloy part milling considering its geometry and fixtures
(Elsevier, 2022-11)
The aeronautic industry is facing many challenges regarding the lifetime, weight and accuracy that aircraft skins must comply to meet stringent structural and aerodynamic requirements. Currently, mechanical milling of ...
Effects of Mn addittion, cooling rate and holding temperature on the modification and purification of iron-rich compounds in AlSi10MnMg(Fe) alloy
(Elsevier, 2023-02)
The use of secondary aluminum alloys in industry is still limited by the high Fe contents in recycled alloys. In general, the Fe-rich intermetallic compounds deteriorate the performance of secondary Al–Si alloys, specially ...
Frictional contact analysis in a spherical roller bearing
(Oxford University Press, 2023-02)
Numerical analyses of the roller–raceway contact have been carried out in a spherical roller bearing using frictional contact models of different complexity. The models used in the study include an implementation of Kalker’s ...

Drilling Process in γ-TiAl Intermetallic Alloys
(MDPI, 2018-11-26)
Gamma titanium aluminides (gamma-TiAl) present an excellent behavior under high temperature conditions, being a feasible alternative to nickel-based superalloy components in the aeroengine sector. However, considered as a ...
Optimum dimensional synthesis using GIMSYNT software
(Springer, 2019-06-14)
In the field of mechanism design, optimum dimensional synthesis
plays a significant role. Focusing on path generation synthesis, the designer has
to find the most adequate mechanism capable of tracing a trajectory as ...
Dynamics and mechanical vibrations. Complementing the theory with virtual simulation and experimental analysis
(Springer, 2018-09-21)
The purpose of the present work is to show how the complex theory in subjects related to
Mechanism and Machine Theory can be reinforced with some practicals in which the students can perform
virtual simulation of the ...
Prediction Methods and Experimental Techniques for Chatter Avoidance in Turning Systems: A Review
(MDPI, 2019-11)
The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for ...
Hole Making by Electrical Discharge Machining (EDM) of -TiAl Intermetallic Alloys
(MDPI, 2018-07)
Due to their excellent strength-to-weight ratio and corrosion and wear resistance, gamma-TiAl alloys are selected for aerospace and automotive applications. Since these materials are difficult to cut and machine by ...
