Multi-Response Optimization of WEDM Process Parameters for Machining of Superelastic Nitinol Shape-Memory Alloy Using a Heat-Transfer Search Algorithm
(MDPI, 2019-04-18)
Nitinol, a shape-memory alloy (SMA), is gaining popularity for use in various applications. Machining of these SMAs poses a challenge during conventional machining. Henceforth, in the current study, the wire-electric ...
On-Line Monitoring of Blind Fastener Installation Process
(MDPI, 2019-04-01)
Blind fasteners are of special interest for aircraft construction since they allow working on joints where only one side is accessible, as is the case in many common aerospace box-type structures, such as stabilizers and ...
Wear Mechanisms and Wear Model of Carbide Tools during Dry Drilling of CFRP/TiAl6V4 Stacks
(MDPI, 2019-09-04)
The present contribution on tool wear during the drilling of carbon fiber composite materials (CFRP)/Ti stacks intends to determine (i) if the adhesion of titanium to carbide is mechanical or chemical, (ii) the possible ...
Thin-Wall Machining of Light Alloys: A Review of Models and Industrial Approaches
(MDPI, 2019-06-23)
Thin-wall parts are common in the aeronautical sector. However, their machining presents serious challenges such as vibrations and part deflections. To deal with these challenges, different approaches have been followed ...
Application of model updating techniques to turbomachinery rotor components
(Sage, 2019-07-12)
Model updating techniques are commonly used to improve simulation accuracy. Experimental data of component testing under laboratory conditions are normally used to improve analytical predictions of that component under ...

(2019-03-01)
Los tratamientos de superficie basados en tecnologías de plasma ofrecen un amplio abanico de posibilidades para el desarrollo de soluciones a problemas tribológicos (fricción, desgaste, etc.). Por otra parte, la combinación ...
Optimization of Planar Mechanisms by using a Minimum Distance Function
(Elsevier, 2019-08)
The paper examines the application of a general minimum distance error function to the
dimensional kinematic synthesis of bidimensional mechanisms. The minimum distance ap-
proach makes it possible to solve the problem ...
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 ...
Metholology for hybrid manufacturing of turbomachinery integral rotary components in thermoresistant super alloys.
(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, ...
