Damping in ram based vertical lathes and portal machines
(Elsevier, 2022)
Chatter vibrations originated by the machine structure are a major limitation for the productivity of ram based machines performing heavy duty operations. Consequently, the damping of the machine structure has a capital ...
Multiscale simulation of volumetric wear of vitrified alumina grinding wheels
(Elsevier, 2023-10)
Wear of vitrified alumina wheels is a major research issue. Although extensive experimental work has been presented in the scientific literature, wheel manufacturers and grinding users are still unable to predict the ...
Robotic-Arm-Based Force Control by Deep Deterministic Policy Gradient in Neurosurgical Practice
(MDPI, 2023-09-30)
This research continues the previous work “Robotic-Arm-Based Force Control in Neurosurgical Practice”. In that study, authors acquired an optimal control arm speed shape for neurological surgery which minimized ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Gurney Flap Implementation on a DU91W250 Airfoil
(MDPI, 2018-11-06)
Abstract
The increasing capability of Wind Turbine (WT) based power generation systems has derived in an increment of the WT rotor diameter, i.e., longer rotor blades. This results in an increase of the electrical power ...
Drilling of CFRP-Ti6Al4V stacks using CO2-cryogenic cooling
(Elsevier, 2021-04)
In the work here presented, liquefied CO2 is used as cutting fluid for drilling CFRP-Ti6Al4V stacks as alternative to dry-drilling. Several tests were performed using dry-drilling technique, to compare this with the ...
Tool wear monitoring of high-speed broaching process with carbide tools to reduce production errors
(Elsevier, 2022-06)
Real-time monitoring in CNC machine tools is focused on the early detection of tool wear, and in this way to assess part piece quality. The machining process known as broaching is critical for firtree slots (dovetails) ...
In pursuit of sustainable cutting fluid strategy for machining Ti-6Al-4V using life cycle analysis
(Elsevier, 2021-09)
The need for developing sustainable manufacturing processes which should have a good balance between economic viability and environmental protection is one of the key challenges against manufacturers. The conventional ...
Sustainable Alternative of Structural Concrete Retaining Tanks
(Emerald Publishing, 2018-05)
The environmental footprint of the construction industry requires the quantification of new developments to appraise their sustainable contribution. Recent developments in relation to the merging of steel fibre reinforced ...
Study of historical developments in the use of fire resistant steels
(Taylor&Francis, 2014-10-29)
This paper presents a review of the most relevant articles on fire-resistant (FR) steels, as part of a research project at the University of the Basque Country (UPV/EHU) on the FR properties of steelstructures. An important ...
