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 ...
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 ...

(2024-02-16)
La fabricación aditiva mediante arco e hilo (wire arc additive manufacturing, WAAM) es uno de los procesos de fabricación aditiva de metales que ha despertado un interés creciente en los últimos años como viable alternativa ...
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 ...
Advanced Control Strategies for Wind Power Generation with Floating Technology.
(2024-02-19)
El consenso entre expertos internacionales es claro: las actividades humanas están acelerando el calentamiento global y el cambio climático. Somos muy conscientes de nuestras demandas energéticas, y es evidente que una ...
Stiffening near-net-shape functional parts of Inconel 718 LPBF considering material anisotropy and subsequent machining issues
(Elsevier, 2021-12-24)
[EN] Additive manufacturing of metallic parts has witnessed significant development. The laser powder bed fusion (LPBF) process has emerged as a key process for manufacturing thin-walled components. However, despite the ...
