A Methodology to Evaluate the Reliability Impact of the Replacement of Welded Components by Additive Manufacturing Spare Parts
(MDPI, 2019-08-26)
This article shows a method for inspection scheduling of structures made by additive manufacturing, derived from reliability function evaluations and overhaul inspection findings. The routine was an adaption of an existing ...
Development of an Intra-Layer Adaptive Toolpath Generation Control Procedure in the Laser Metal Wire Deposition Process
(MDPI, 2019-02-01)
Recently developed concentric laser metal wire deposition (LMWD) heads allow metal addition processes which are independent of the deposition direction, thus enabling complex paths to be generated. The sensitivity of the ...

(2019-11-28)
El principal objetivo de esta tesis doctoral consiste en abordar de manera conjunta las diferentes etapas dentro de la cadena de producción de fabricación híbrida (aditiva y sustractiva) de componentes de alto valor añadido, ...
Inspection scheduling based onreliability updating of gas turbinewelded structures
(Sage, 2019-01-28)
This article presents a novel methodology for the inspection scheduling of gas turbine welded structures, based on reliability calculations and overhaul findings. The model was based on a probabilistic crack propagation ...
Design of an active reconfigurable 2R joint
(Springer, 2019-06-14)
The increasing flexibility requirements in the manufacturing processes has led to the development of novel reconfigurable mechanisms to be implemented in ma-chine heads and tables. This is the case of the reconfigurable ...
Experimental and numerical analysis of wear flat generation and growth in alumina grinding wheels.
(2019-03-22)
El proceso de rectificado supone entre un 20-25% del coste total de fabricación, suponiendo el consumo de muela un porcentaje muy elevado del coste total. De entre los diferentes tipos de desgaste, el wear flat es el más ...
An active/passive joint for reconfiguration applications
(Springer, 2019-09-07)
In this paper, an active/passive reconfigurable 2R joint is presented. Direct and inverse kinematic problems and the force transmission are considered. The advantages of the current design show its superiority with respect ...
Flexural Strength Prediction Models for Soil–Cement from Unconfined Compressive Strength at Seven Days
(MDPI, 2019-01-26)
Soil⁻cement is an environmentally friendly road construction technique for base and subbase materials, which allows employing soils placed in the right-of-way of the road or in the surroundings, by improving its engineering ...
Advances in the Study of the Behavior of Full-Depth Reclamation (FDR) with Cement
(MDPI, 2019-08-01)
Road maintenance and rehabilitation are expected to meet modern society's demands for sustainable development. Full-depth reclamation with cement as a binder is closely linked to the concept of sustainability. In addition ...
Advanced Manufacturing Centres, Practical Model to Boost Technology Transfer in Manufacturing
(MDPI, 2019-09)
Establishing collaboration strategies with interdisciplinary networks in research is a crucial success factor for the companies in any sector, especially in manufacturing for aeronautics. In the aeronautical supply chain, ...
