Alternative experimental methods for machine tool dynamics identification: A review
(Elsevier, 2022-05-01)
An accurate machine dynamic characterization is essential to properly describe the dynamic response of the machine or predict its cutting stability. However, it has been demonstrated that current conventional dynamic ...
Requirements and Solutions for Motion Limb Assistance of COVID-19 Patients
(MDPI, 2022)
COVID-19 patients are strongly affected in terms of limb motion when imbedded during the acute phase of the infection, but also during the course of recovery therapies. Peculiarities are investigated for design requirements ...
The effect of preforming and infusing bindered and unbindered carbon non-crimp-fabrics on the final quality of composites parts
(Elsevier, 2022)
[EN] Vacuum infusion (VI) is a liquid moulding process used to manufacture fibre-reinforced polymer composite parts. The VI process for non-crimp fabric (NCF) preforms is one of the most promising processes for improving ...
Numerical Modeling of the Influence of Nanometric Ceramic Particles on the Nucleation of AlSi10MnMg Alloy
(MDPI, 2022-05-17)
In recent years, many researchers have attempted to model the solidification process of nano-reinforced materials. In the present document, the effect on the heterogeneous solidification regime of the different sizes, ...
Tool Wear Effect on Surface Integrity in AISI 1045 Steel Dry Turning
(MDPI, 2022-03-09)
In the present work, the surface integrity and flank wear of uncoated cermet inserts in dry turning of AISI 1045 steel were evaluated. Three-dimensional techniques were used to assess the surface roughness. Previously, ...
Effect of the geometry of butt-joint implant-supported restorations on the fatigue life of prosthetic screws.
(Elsevier, 2022-03)
[EN] STATEMENT OF PROBLEM: Dental implant geometry affects the mechanical performance and fatigue behavior of butt-joint implant-supported restorations. However, failure of the implant component has been generally studied ...
A dynamic data driven application system for real-time simulation of resin transfer moulding processes
(Springer, 2022)
[EN] This paper presents a numerical solution to optimize RTM processes based on a DDDAS methodology, taking permeability as stochastic. The model proposed in this investigation allows real-time accurate prediction of the ...
Improvement of boring operations by means of mode coupling effect
(Elsevier, 2022-05)
Boring bars are inherently slender tools which are prone to show chatter problems due to their low dynamic stiffness and damping, being this problem their main limitation in productivity. The onset of chatter is mainly ...
Conceiving a Digital Twin for a Flexible Manufacturing System
(MDPI, 2022-09-30)
Digitization and virtualization represent key factors in the era of Industry 4.0. Digital twins (DT) can certainly contribute to increasing the efficiency of various productive sectors as they can contribute to monitoring, ...
Fatigue improvement and residual stress relaxation of shot-peened alloy steel DIN 34CrNiMo6 under axial loading
(Elsevier, 2022-09)
Shot-peening treatment was applied to a quenched and tempered DIN 34CrNiMo6 steel to improve its high-cycle R: -1 axial fatigue strength. Compared with the machined condition, the increase in the fatigue limit was 21.8%. ...
