EDM, or electrical discharge machining, is a process that uses electric sparks to erode material by creating a spark between an electrode and workpiece. This spark reaches extremely high temperatures of 8,000-12,000°C and precisely machines complex geometries in hard metals. An EDM drilling machine uses this process to drill micro-holes from 0.3-6mm in diameter and up to 300mm deep in metals. It mounts the workpiece, selects an electrode, and supplies power and dielectric fluid to create a controlled spark and remove material, drilling holes for applications like wire EDM starters, gas escapes, and cooling pins.

production rates; high tooling costs.
Stretch forming
Large parts with shallow contours; suitable for low-quantity production; high
labor costs; tooling and equipment costs depend on part size.

high tooling and equipment costs.
Stamping Includes a variety of operations, such as punching, blanking, embossing,
bending, flanging, and coining; simple or complex shapes formed at high

are low.

forming
Complex shapes, fine detail, and close tolerances; forming times are long,
and hence production rates are low; parts not suitable for high-temperature
use.

Electrical Discharge Machine is an advanced machining method which removes metal by a series of recurring electrical discharges betweenn an electrode and a conductive workpiece, submerged in a dielectric fluid.
Experimental Investigation of Electrode Wear in Die-Sinking EDM on Different ...IJMER
EDM is an advanced machining method for manufacturing, hard material parts which
are difficult to machine by conventional machining process. There are various type of products which
can be produced by using Die-sinking EDM, such as dies, moulds. Parts of aerospace, automobile
industry and surgical components can be finished machined by EDM. In present scenario numbers of
researchers have explored a number of ways to improve EDM efficiency. The optimum selection of
manufacturing condition is very important in manufacturing processes as they determine surface
quality, dimensional accuracy of the obtained parts. This experimental investigation is mainly focused
on electrode wear in cylindrical copper electrode on different pulse-on & off time (µs) at constant
current(amp.) which is an important parameter. In this experimental work, an investigation has been
made to optimize the response parameter (electrode wear) of EDM on die-steel with electrolytic
cylindrical copper electrode. Die-steel (HRC-58) is widely used in production of dies. In this
investigation copper has been taken as electrode and die-steel as a work piece. Electrode wear has
been investigated in the form of weight (gm) and length (mm.) of electrode on different input process
parameters. viz constant discharge current (amp.), pulse on time (T-on), pulse off time (T-off)

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

2. What is EDM: EDM stands for
electrical discharge machining.
•An electrical spark is created
between an electrode and a
workpiece.
•The spark is visible evidence of
the flow of electricity.
•This electric spark produces
intense heat with temperatures
reaching 8000 to 12000 degrees
Celsius, melting almost anything.
•The spark is very carefully
controlled and localized so that it
only affects the surface of the
material
