Optimization of MRR in EDM Process with Different Job Material i.e Stainless ...IJERA Editor
Electro discharge machining (EDM) has been recognized as an efficient method of producing dies and machining of hard material such as ceramics and high strength metal matrix composites for the modern metal industry (1). In this process the metal are remove through melting or vaporization of job metal by high frequency spark discharge. Although in this process the metal removal rate is lower than the other non-conventional machining process. But the dimensional accuracy is higher than the other process and more complex shape can be produce generally composite material are fascinated as thy exhibit exceptional mechanical and physical properties such as high strength, high hardness, and high density at elevated temperature. For this extra ordinary behavior it has wide range of application on the metal industries like aerospace, dies or mould making industries, automobiles industries etc. The metal removal rate (M.R.R.) and surface smoothness not only depend on the selection of tool material also depend on the number of input parameter (such-input current, voltage, spindle speed, duty factor, dielectric medium), job metal property (conductivity ,hardness, strength, density etc.),machine condition and machining condition(machine performances, temperature, depth of cut or area of cut etc.). It is most difficult to select machining condition for optimal performances due to large number of parameters and inherent complexity of material removal mechanism taking place in EDM process. In the present work, the experiments were conducted using Taguchi L9 orthogonal approach, to ascertain the effect of EDM process parameters on material removal rate (MRR) of stain less steel and cast iron by using tool material such copper and graphite.
A Comparative Study to Maximize MRR in Electro Discharge Machining Process by...IJERA Editor
Electro Discharge Machining (EDM) is a non-traditional machining process, based on thermo electric energy between the work piece and electrode. In this process, the material removal is occurred electro thermally by a series of successive discrete discharges between electrode and the work piece. Electro Discharge Machine which has the ability to machine hard, difficult to machine material and parts with internal complex shape by using precisely controlled sparks that occurs between electrode and work piece in the presence of dielectric fluid. This spark removes material from both work piece and electrode. Material Removal Rate (MRR) is of crucial importance in this process. In this research experiment has been done along with Copper and Graphite tool material as well as Mild Steel and Aluminium material has been used as work piece. Three major Parameters named as Electrode Speed (V), Current (I), and Depth of Cut (h) are considered to determine the MRR. In this experiment three levels of each parameter has been taken by using Taguchi L9 orthogonal array to find out the best combination of electrode and work piece at the optimal setting of control parameters for maximum Material Removal Rate.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
