Finite Element Prediction of the Tool Wear Influence in Ti6Al4V Machining
(Elsevier, 2015)
Ti6Al4 V is a titanium alloy widely used in the aeronautical industry and machining is often adopted to manufacture it. These parts must satisfy requirements specified by the customer. A crucial characteristic of aircraft ...
Machining behaviour of Ti-6Al-4V and Ti-5553 alloys in interrupted cutting with PVD coated cemented carbide
(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 ...
Evolution of Surface Roughness in Grinding and its Relationship with the Dressing Parameters and the Radial Wear
(Elsevier, 2013)
Grinding is a machining process specially indicated for finishing operations in hard materials, in order to obtain low surface roughness (Ra 0.1 μm to 2μm) and tight tolerances. The cutting tool is the grinding wheel which ...
Effect of heat Treatment Conditions on the Machinability of Ti64 and Ti54 M Alloys
(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 ...
Phase transformation fronts propagation during the Stress Induced Martensitic transformation in NiTi Shape Memory Alloy wires at impact strain rates
(EDP Sciences, 2009)
Propagation of phase transformation fronts during the stress induced martensitic (SIM) transformation at impact strain rates, on the order of 10 s-1, was observed in situ by measuring changes in infrared radiation on the ...
Relationship between the use of ICT and the degree and type of diversification
(Elsevier, 2016)
Advances in information and communication technologies (ICT) has given way to a new genre of opportunities for companies expanding their horizons to explore new markets and to diversify their business. In this sense, the ...
An Accurate Shock Advise Algorithm for Use During Piston-Driven Chest Compressions
(IEEE, 2018)
Mechanically delivered chest compressions induce artifacts in the ECG that can lead to an incorrect diagnosis of the shock advice algorithms implemented in the defibrillators. This forces the rescuer to stop cardiopulmonary ...
Sustainability analysis on Urban Mobility based on Social Media content
(Elsevier B.V., 2017)
Urban transport became an important element in the promotion of strategies towards sustainability, in fact one of the challenges posed by booming urban populations is the question of mobility. Traditional travel survey ...
Seeding Strategies for Multi-Objective Test Case Selection: An Application on Simulation-based Testing
(ACM, 2020)
The time it takes software systems to be tested is usually long. This is often caused by the time it takes the entire test suite to be executed. To optimize this, regression test selection approaches have allowed for ...
Vibration attenuation of conductive beams by inducing eddy currents
(IOP, 2016)
The increasing requirements for structural vibration control in many industries, require innovative attenuation techniques. In this work, the phenomenon of eddy currents is proposed to reduce the ...
