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 ...
Análisis de las condiciones de mecanizado, geometría de pieza y secuencia de fresado en la fabricación de piezas aeronáuticas de bajo espesor con sujeción local
(2023-02-21)
Las piezas de aleación de aluminio son ampliamente utilizadas en el sector aeronáutico, entre otros, para los componentes de cobertura y pieles del fuselaje. Estas piezas suelen ser muy delgadas y por lo tanto su rigidez ...

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 ...
Five MegawattWind Turbine Power Output Improvements by Passive Flow Control Devices
(MDPI, 2017-06)
The effects of two types of flow control devices, vortex generators (VGs) and Gurney flaps (GFs), on the power output performance of a multi-megawatt horizontal axis wind turbine is presented. To that end, an improved blade ...
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, ...
Kinematic Analysis of three degrees of freedom planar parallel continuum mechanisms
(Elsevier, 2023-07)
Parallel continuum mechanisms are a type of compliant mechanisms comprising a rigid end-effector connected to a fixed frame by flexible and slender elements in a closed-kinematic morphology, being their flexibility the ...
