LASER BEAM MACHINING - NON TRADITIONAL MACHININGSajal Tiwari
Laser Beam Machining or more broadly laser material processing deals with machining and material processing like heat treatment, allowing, cladding, sheet metal bending etc. Such processing is carried out utilizing the energy of coherent photons or laser beam, which is mostly converted into thermal energy upon interaction with most of the materials. Nowadays, the laser is also finding application in regenerative machining or rapid prototyping as in processes like stereolithography, selective laser sintering etc. Laser stands for light amplification by stimulated emission of radiation. The underline working principle of a laser was first put forward by Albert Einstein in
1917 through the first industrial laser for experimentation was developed around the 1960s. The laser beam can very easily be focused using optical lenses as their wavelength ranges from half a micron to around 70 microns. The focused laser beam as indicated earlier can have power density in excess of 1 MW/mm2 . As laser interacts with the material, the energy of the photon are absorbed by the work material leading to a rapid substantial rise in local temperature. This, in turn, results in melting and vaporization of the work material and finally material removal.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

2. EDM (Electrical discharge machining)
-Principle
• A thin wire of round shape used as an electrode, which is
supplied to the work area through a pair of wheels. With the
aid of current a high power spark is produced between wire-
electrode and work piece. Due to this high amount of heat is
produced nearly to 10000 degree Celsius. This heat energy
used to melt and vaporize the work material. Then with the
supply of dielectric fluid the molten stage materials are flushed
away, likewise the machining is carried out in the work piece.

It’s a mixture of Free electrons + Partially ionized gas
and Neutral Atoms
82. Direct Arc Plasma Torch
PILOT ARC
A Pre arc (Pilot arc) is
created b/w electrode and
nozzle
when this pre arc touches the
work piece the current flows
from work piece to electrode .
This make main arc b/w
electrode and work piece. So
now pre –Arc is switched off
83. Transferred arc process
Direct Arc Plasma Torch
• The arc is formed between the electrode(-) and the work piece(+).
• In other words, arc is transferred from the electrode to the work
piece.
• A transferred arc possesses high energy density and plasma jet
velocity. For this reason it is employed to cut and melt metals.
Besides carbon steels this process can cut stainless steel and
nonferrous metals also where oxyacetylene torch does not
succeed. Transferred arc can also be used for welding at high arc
travel speeds. A pilot arc is established between the electrode and
the nozzle. As the pilot arc touches the job main current starts
flowing between electrode and job, thus igniting the transferred
arc. The pilot arc initiating unit gets disconnected and pilot arc
extinguishes as soon as the arc between the electrode and the job
is started. The temperature of a constricted plasma arc may be of
the order of 8000 - 250000C.
85. Non-transferred arc process
In-Direct Arc Plasma Torch
• The arc is formed between the electrode(-) and the water cooled
nozzle(+).
• Arc plasma comes out of the nozzle as a flame.
• The arc is independent of the work piece and the work piece does
not form a part of the electrical circuit. Just like an arc flame (as in
atomic hydrogen welding), it can be moved from one place to
another and can be better controlled. The non transferred plasma
arc possesses comparatively less energy density as compared to a
transferred arc plasma and it is employed for welding and in
applications involving ceramics or metal plating (spraying). High
density metal coatings can be produced by this process. A non-
transferred arc is initiated by using a high frequency unit in the
circuit.
