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 ...
Towards a Taxonomy for Eliciting Design-Operation Continuum Requirements of Cyber-Physical Systems
(IEEE, 2020)
Software systems that are embedded in autonomous Cyber-Physical Systems (CPSs) usually have a large life-cycle, both during its development and in maintenance. This software evolves during its life-cycle in order to ...
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 ...
Finding correlations between tool life and fundamental dry cutting tests in finishing turning of steel
(Elsevier, 2015)
Tool life is usually measured by end tool life tests, however, such experiments are costly and time consuming. Establishing correlation between these tests and shorter and cheaper tests is consequently of great interest. ...
Personalised Trachea Stent Designer: a Knowledge Feature
(Elsevier, 2012)
Modelling of anatomical parts is usually tackled through triangulated models with specialised Bio-CAD applications. If features beyond anatomy are required, geometry is usually translated into NURBS geometry for further ...
Roll levelling semi-analytical model for process optimization
(IOP, 2016)
Roll levelling is a primary manufacturing process used to remove residual stresses and imperfections of metal strips in order to make them suitable for subsequent forming operations. In the last years the importance of ...
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 ...
