Honeycomb Grinding Using Spark Erosion
Grit Blasting for Removal of Recast Layer from EDM Process ...
· The heat generated during EDM melts the work material and thereby allows large amounts to be removed, but an unfavorable surface of a recast layer (RCL) will also be created. This layer has entirely different properties compared to the bulk. Hence, it is of great interest to efficiently remove this layer and to verify that it has been removed. The main objective of this work has been to study ...

A spark erosion apparatus
Other workers ( Eric Rumbo in an article entitled "A simple spark erosion machine", Model Engineers's Wokshop 117, July 2006) have attempted to drive the solenoid independently of the charge discharge circuit using an astable multivibrator based on the 555 chip. This enables the charge discharge circuit to be optimised for good sparking but being a constant frequency the coil drive does ...

RG | Precision Engineering Limited
In wire electrical discharge machining (WEDM), or wirecut EDM, a thin singlestrand metal wire, usually brass, is fed through the workpiece, typically occuring submerged in a tank of ELECTRIC fluid. This process is used to cut plates as thick as 300mm and to make punches, tools and dies from hard metals that are too difficult to machine with ...

Angle Grinder Safety Tips to Prevent Accidents
So accidental fire won't occur unless the grinding sparks fall continuously at one spot on a flammable material. But it's also better to be safe than sorry, so make sure that there isn't any flammable material near you when using the angle grinder. Disc Debris – The Major Cause of Angle Grinder Accidents . A far more serious danger to be wary of when using your angle grinder is ...

Fuzzy logicbased model for predicting material removal ...
· Mechanism of machining involves the mechanical abrasion of workpiece resulting owing to grinding action and spark erosion of workpiece due to electric discharge action. Further, the addition of abrasives/powder in the dielectric fluid results in reduced breakdown stability of dielectric fluid. Thus, the gap contamination promotes the ignition and increases the gap size. A chain of discharges ...
Spark Erosion: Electrode Selection (Spark Erosion)
· Due to its high rate of wear, brass is no longer a viable electrode material for spark erosion use (with the exception of smalldiameter tubing for EDM hole drilling). Tellurium Copper. The most commonly used metallic electrode material. The element tellurium has been added ( to 1%) for ease of machining. It has acceptable metal removable rates and reasonable wear. Sometimes called "Telco ...
What is Spark Erosion? | Dean Group International
· There are several factors to keep in mind when using spark erosion, like the material of the electrodes, their design and their manufacture. The Advantages of Spark Erosion. Spark erosion allows a company to achieve intrie details that would, otherwise, be too complex or impossible to obtain with traditional cutting methods and is especially useful for alterations to hard materials such as ...

Material Removal Rate
Using these values for b and G c, u f ≈ J/mm 3, which is only about 1% of the specific grinding energy. Some specific energy measurements are shown in Figure , which range from about 100 J/mm 3 at low removal rates down to about 40 J/mm 3 at high removal rates.
The Effects of ErosionCorrosion on Power Plant Piping
Typically, zero beam ultrasonics (UT) is used, although radiography (RT) is an option. Another option is to use crawlers and TV cameras to examine the piping inner surface. Factors mitigating erosioncorrosion which are under the control of the plant owner are the pH(> is best), oxygen content (50ppb), and pipe material (a steel is very resistant to singlephase erosioncorrosion ...
Drilling Small, Deep Holes with Precision EDM
· Electrical Discharge Machining (EDM) has been removing metal by spark erosion for more than half a century—with sinker (ram/Elox) style EDMing for molds and wire EDM for precision parts cutting, especially dies. A third type, EDM drilling, has emerged for precision holemaking in the smallest sizes, going beyond its use initially as an EDM "popper" for starting holes in hard metals.
