Effect of powder particle size distribution on the surface finish of components manufactured by laser powder bed fusion
(Springer, 2023)
One of the key aspects of the laser powder bed fusion (L-PBF) process is the quality of the raw powder since it affects the final properties of the manufactured parts. In this study, 13 batches of Inconel (R) 718 powder ...
Strain Virtual Sensing for Structural Health Monitoring under Variable Loads
(MDPI, 2023-05-12)
Virtual sensing is the process of using available data from real sensors in combination with a model of the system to obtain estimated data from unmeasured points. In this article, different strain virtual sensing algorithms ...
Investigating the effect of novel self-lubricant TiSiVN films on topography, diffusion and oxidation phenomenon at the chip-tool interface during dry machining of Ti-6Al-4V alloy
(Elsevier, 2023-08)
Machining of titanium alloys such as Ti-6Al-4 V can be very intimidating due to their low thermal conductivity leading to elevated cutting temperatures at the chip-tool interface (ICT). In this regard, the self-lubrication ...
Predicting rail corrugation in a real line by means of a fast non-linear vertical and lateral model
(Elsevier, 2023-07)
This work is the result of a problem of premature development of rail corrugation found on a new metro line. As urgent solutions, a rail grinding was carried out and friction modifier started to be applied. Experimental ...
The Effect of Cooling Temperature on Microstructure and Mechanical Properties of Al 6061-T6 Aluminum Alloy during Submerged Friction Stir Welding
(MDPI, 2023-06-22)
Submerged friction stir welding (SFSW) is a new modification of friction stir welding. In this paper, 6 mm thick 6061Al-T6 alloy plates were welded using the friction stir technique under normal air and submerged water ...
Assessing Industrial Communication Protocols to Bridge the Gap between Machine Tools and Software Monitoring
(MDPI, 2023-06-18)
Industrial communication protocols are protocols used to interconnect systems, interfaces, and machines in industrial environments. With the advent of hyper-connected factories, the role of these protocols is gaining ...
Calculation of Linear Buckling Load for Frames Modeled with One-Finite-Element Beams and Columns
(MDPI, 2023-05-30)
Critical linear buckling load calculation is one of the possible ways to check structural stability. Structural analysis programs usually model beams and columns with just one element, but this is not enough to obtain an ...
Development and Mechanical Characterization of Ni-Cr Alloy Foam Using Ultrasonic-Assisted Electroplating Coating Technique
(MDPI, 2023-05-28)
Metal foams and alloy foams are a novel class of engineering materials and have numerous applications because of their properties such as high energy absorption, light weight and high compressive strength. In the present ...
Robotic-Arm-Based Force Control in Neurosurgical Practice
(MDPI, 2023-02-06)
This research proposes an optimal robotic arm speed shape in neurological surgery to minimise a cost functional that uses an adaptive scheme to determine the brain tissue force. Until now, there have been no studies or ...
An accuracy evolution method applied to five-axis machining of curved surfaces
(Springer, 2023-04)
Currently, some high-value-added applications involve the manufacturing of curved surfaces, where it is challenging to achieve surface accuracy, repeatability, and productivity simultaneously. Among free-form surfaces, ...
