Vision-Based Hybrid Controller to Release a 4-DOF Parallel Robot from a Type II Singularity
(MDPI, 2021-06-13)
The high accuracy and dynamic performance of parallel robots (PRs) make them suitable to ensure safe operation in human–robot interaction. However, these advantages come at the expense of a reduced workspace and the possible ...
Machining Stresses and Initial Geometry on Bulk Residual Stresses Characterization by On-Machine Layer Removal
(MDPI, 2020-03-22)
Prediction and control of machining distortion is a primary concern when manufacturing monolithic components due to the high scrap and rework costs involved. Bulk residual stresses, which vary from blank to blank, are a ...
Optimización del proceso de fabricación de utillajes de conformado en caliente mediante el cálculo del mapa térmico de la pieza estampada
(2021-01-25)
El objetivo de este trabajo de investigación es desarrollar una metodología de optimización de superficiesde mecanizado de troquel mediante la predicción de deformaciones térmicas debidas a un mapa detemperaturas heterogéneo ...
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. ...
In service behavior of components repaired by laser cladding - Process, microstructure and fatigue behavior relationships
(2021-09-16)
Durante esta tesis se ha desarrollado:1. Un modelo analítico del proceso de revestimiento por láser para la aleación Inconel 718, tomando en cuenta las propiedades dependientes de la temperatura y aplicable a otros materiales ...
Identification of Key Performance Indicators in Project-Based Organisations through the Lean Approach
(MDPI, 2020-07-24)
For the time being, companies and organisations are being forced to compete in utterly complex and globalised environments, facing massive natural, economic, and technological challenges on a daily basis. Addressing these ...
Statistical Approach for the Design of Structural Self-Compacting Concrete with Fine Recycled Concrete Aggregate
(MDPI, 2020-12-09)
The compressive strength of recycled concrete is acknowledged to be largely conditioned by the incorporation ratio of Recycled Concrete Aggregate (RCA), although that ratio needs to be carefully assessed to optimize the ...
The Effect of the Laser Incidence Angle in the Surface of L-PBF Processed Parts
(MDPI, 2020-10-24)
The manufacture of multiple parts on the same platform is a common procedure in the Laser Powder Bed Fusion (L-PBF) process. The main advantage is that the entire working volume of the machine is used and a greater number ...
CO2 cryogenic milling of Inconel 718: cutting forces and tool wear Author links open overlay panel
(Elsevier, 2020-07)
Machining Inconel 718 alloy is a challenge due to its low machinability. This thermal resis-tant alloy combines high strength even at high temperatures with strain hardening tendency that causes high forces and extreme ...
Lime mud waste from the paper industry as a partial replacement of cement in mortars used on radiant floor heating systems
(Elsevier Ltd., 2021-03-13)
[EN] In order to mitigate climate change, reductions of energy consumption are required on heating systems for residential and non-residential buildings. Despite radiant floor heating systems are being widely used due to ...
