Electric discharge machining (EDM) is a process that removes small amounts of material from electrical contacts using electrical sparks. For efficient machining, short, high frequency sparks are needed. The sparks can be concentrated into a small area if the discharge is submerged in a dielectric fluid using a relaxation circuit. EDM is a thermoelectric process that uses the heat from sparks to remove material from the workpiece. EDM involves removing material from a conductive workpiece using electrical discharges between two electrodes submerged in a dielectric fluid.

Current Advanced Research Development of Electric Discharge Machining (EDM): ...sushil Choudhary
Electrical discharge machining (EDM) process is one of the most commonly used nonconventional
precise material removal processes. Electrical discharge machining (EDM) is a process for
shaping hard metals and forming deep complex shaped holes by arc erosion in all kinds of electroconductive
materials. Erosion pulse discharge occurs in a small gap between the work piece and the
electrode. This removes the unwanted material from the parent metal through melting and vaporizing in
presence of dielectric fluid. In recent years, EDM researchers have explored a number of ways to improve
EDM Process parameters such as Electrical parameters, Non-Electrical Parameters, tool Electrode based
parameters & Powder based parameters. This new research shares the same objectives of achieving more
efficient metal removal rate reduction in tool wear and improved surface quality. This paper reviews the

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Sparking takes place between two electrical contacts a
small amount of material is removed from each of the
contacts. This facts was realized and the attempts
were made to harness and control the spark energy to
employ it for useful purpose , say, for machining of
metals. It was found that the sparks of short duration
and high frequency are needed for efficient
machining.
3. It was also observed that if the discharged is
submerged in dielectric , the energy can be
concentrated into a small area . A relaxation circuit
(Known as RC circuit ) was proposed in which
electrodes (tool and work piece ) are immersed in the
dielectric like kerosene , and are connected to the
capacitor. EDM is a thermoelectric process in which
heat energy of a spark is used to remove material from
the work piece.
4. Electric Discharge Machining (EDM) is the removal of
materials conducting electricity by electrical discharge
between two electrodes (work piece electrode and tool
electrode ), a dielectric fluid being used in the process.
6. In this case, the metal removal is affected by non
stationary electrical discharges which are separated
from each other both spatially and temporarily. This
process includes those EDM operation in which the
average relative speed between the tool and work piece
is coincident with the penetration speed in the work
piece.
7. It includes these machining operations where the work
piece is cut off or notched.
8. Spark erosion grinding embraces the machining
processes made with an electrode rotating around an
axis in addition to the normal electrode feed.
