An accuracy evolution method applied to five-axis machining of curved surfaces
(Springer, 2023-04)
Currently, some high-value-added applications involve the manufacturing of curved surfaces, where it is challenging to achieve surface accuracy, repeatability, and productivity simultaneously. Among free-form surfaces, ...
Kinematic Analysis of three degrees of freedom planar parallel continuum mechanisms
(Elsevier, 2023-07)
Parallel continuum mechanisms are a type of compliant mechanisms comprising a rigid end-effector connected to a fixed frame by flexible and slender elements in a closed-kinematic morphology, being their flexibility the ...
Dynamic control for LMD processes using sensor fusion and edge computing
(Elsevier, 2022-09)
The quality of an LMD manufactured object highly depends on different process parameters such as the speed of powder deposition, the applied laser power, the powder feed rate, and other physical parameters such as the ...
Adaptive control for a dual laser beam solution for the welding of high reflectivity dissimilar materials
(Elsevier, 2022-09)
The laser welding technology delivers high flexibility and adaptability to the welding process being able to adjust to complex joint geometries. Additionally, the application of a laser beam minimises the microstructural ...
Blisk blades manufacturing technologies analysis
(Elsevier, 2020-03-09)
The paper presents blisk blades manufactured by different manufacturing processes. In this sense, different milling trajectories are presented, and, super abrasive machining strategies and EDM technologies are also tested. ...

Effect of Post-Processing Treatment on Fatigue Performance of Ti6Al4V Alloy Manufactured by Laser Powder Bed Fusion
(MDPI, 2023-06-22)
Fatigue properties of parts are of particular concern for safety-critical structures. It is well-known that discontinuities in shape or non-uniformities in materials are frequently a potential nucleus of fatigue failure. ...
A Framework for Climate Resilient Urban Design: The Case of Porte de Montreuil, Paris
(MDPI, 2023-09-18)
With the increasing frequency and intensity of extreme climate events in cities, it is essential to develop multi-scale and multi-hazard design tools to ensure urban climate resilience. A designed approach to urban development ...
