This document describes the development of a single hydraulic cylinder operated sheet metal bending machine. It aims to maximize the forces generated by the hydraulic cylinder to make the machine lighter and less costly.
The key components of the machine include a lever system to convert the horizontal forces from the cylinder into a vertical downward bending force. A link connects the lever to an upper beam that carries the bending load. Through innovative use of the lever and linkage, both the pushing and pulling forces of the hydraulic cylinder can be utilized for bending, rather than having the pulling force wasted.
An analysis is presented to determine the required bending force based on the material properties and dimensions of the sheet being bent. This force calculation is used to design the machine components

This document presents a study on the performance analysis of a vertical axis wind turbine (VAWT) with straight blades (called a Giromill configuration) using computational fluid dynamics (CFD) simulations and experiments.
The study analyzed the effects of parameters like air velocity, angle of attack, and number of blades. The maximum power coefficients from 3D CFD simulations were 30.49% for a 4-blade design and 33.89% for a 6-blade design. Experimental testing showed maximum power coefficients of 25.11% and 27.90% respectively, indicating fair agreement with CFD results. Increasing the number of blades and airflow velocity, and decreasing the angle of attack, led to higher power coefficients in

Novel Design and Model of Punching Machine Driven By Electromagnetic ActuatorIDES Editor
The greatest challenge faced by an engineer is
to overcome the energy wasted due to friction in any
mechanical process. In a conventional punching process,
mechanical or hydraulic force is used to operate the punch
which involves large amounts of metal to metal contact in the
drive system components, as well as inaccuracy in the control
of the punching forces at the micro level. This paper introduces
the basic construction of an Electromagnetic assisted punching
machine to carry out the punching operation. The punching
force is generated by an electromagnetic coil wound around a
metal core. Since the proposed design replaces Mechanical or
hydraulic drive with an electromagnetic actuator, the setup is
capable of perfectly controlling the force generated by the
controlling the power supplied. The micro punching setup is
designed to punch small parts at a precisely controlled rate of
power consumption and thus the process becomes a low friction,
high efficiency process. After successful fabrication, the setup
was tested and the punching force produced was validated.
The punched samples were further analyzed optically for any
defects such as burring and those results were documented.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
