Fundamentals of metal forming processes
The document discusses various metal forming processes used to change the shape of metal workpieces through plastic deformation exceeding the metal's yield strength, including bulk deformation techniques like rolling, forging, and extrusion that involve significant shape changes with lower surface area to volume ratios, and sheet metalworking techniques like bending, drawing, and shearing that are performed on metal sheets or strips with higher surface area to volume ratios. Metal forming is an important manufacturing method that allows for net or near-net shape production, high production rates, profitability, and improved material properties.
Forging
Forging processes involve shaping metals by applying compressive forces. There are four main types: hammer/drop forging uses gravity impacts, press forging uses hydraulic or mechanical presses, and open-die and closed-die forging differ in whether dies fully contain the metal. Forging increases strength by working the metal and altering its microstructure. Proper die and process design are needed to control metal flow, fill dies completely, and minimize flash and defects. Die materials must withstand thermal and mechanical stresses, while coatings can extend die life.
Manufacturing processes
1. Forming is a metalworking process that shapes metal by deforming it without removing material. Common forming processes include rolling, extrusion, forging, and die forming.
2. Joining processes like welding, brazing, and adhesive bonding are used to connect metal components together. Welding involves melting materials to join them, while brazing uses a filler metal below the melting point of the base materials.
3. Machining removes material using tools like lathes, mills, drills and grinders to shape a workpiece. It allows for tight tolerances but incurs significant material removal and waste.

Dr.R.Narayanasamy - Metal forming part - I.
The document discusses various aspects of metal forming processes including strain hardening, work hardening, annealing, cold working, hot working, and the effects of temperature and strain rate on formability.
Some key points include: Strain hardening occurs during metal forming at lower temperatures and increases flow stress. Work hardening is caused by an increase in dislocation density during plastic deformation. Annealing heat treats cold worked metals to restore ductility by reducing dislocation density. Cold working is done below the recrystallization temperature and causes strain hardening, while hot working allows recrystallization during forming. Temperature and strain rate impact formability, with higher temperatures and lower strain rates generally improving formability.

The methodology involves selecting materials, welding process, preparing specimens with varying groove angles, fabricating butt welds, and testing mechanical properties.
Metal rolling
Metal rolling is one of the most important metal forming processes. It involves plastically deforming metal between two rolls to reduce thickness and shape the metal. Most metals are hot rolled into basic shapes like blooms and slabs for further manufacturing. The rolls spin in opposite directions to feed and form the metal through compression. Friction must be controlled through lubrication. Rolling refines grain structure and spreads the width of the metal. Different roll materials, sizes, and mill configurations are used depending on the application. Surface defects can occur if scale or dirt are present while internal defects result from improper material distribution.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
