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 ...
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, ...
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 ...
Experimental evaluation of cement mortars with recycled brass fibres from the electrical discharge machining process
(Elsevier, 2020-06-20)
This paper aims to evaluate the effect of recycled brass fibres on the physical, thermal and mechanical properties of cementitious mortars. For that purpose, seven different mortars, with the same water/cement ratio but ...
Drilling Process in γ-TiAl Intermetallic Alloys
(MDPI, 2018-11-26)
Gamma titanium aluminides (gamma-TiAl) present an excellent behavior under high temperature conditions, being a feasible alternative to nickel-based superalloy components in the aeroengine sector. However, considered as a ...
Optimum dimensional synthesis using GIMSYNT software
(Springer, 2019-06-14)
In the field of mechanism design, optimum dimensional synthesis
plays a significant role. Focusing on path generation synthesis, the designer has
to find the most adequate mechanism capable of tracing a trajectory as ...
Dynamics and mechanical vibrations. Complementing the theory with virtual simulation and experimental analysis
(Springer, 2018-09-21)
The purpose of the present work is to show how the complex theory in subjects related to
Mechanism and Machine Theory can be reinforced with some practicals in which the students can perform
virtual simulation of the ...
Prediction Methods and Experimental Techniques for Chatter Avoidance in Turning Systems: A Review
(MDPI, 2019-11)
The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for ...
