EDM wire cutting
EDM works by creating thousands of sparks. The sparks melt or vaporize the material instead of cutting it. This process works best on non-ferrous metals, such as steel.
Wire EDM uses a thin wire to remove surrounding material, where conventional EDM uses a shaped electrode to remove material.
an edm is a electrode discharge machine. it uses electicity through an electrode to precision cut metal submerged in oil.
I can think of two different things this might be: 1. Dies can be used to make wire. The wire is pulled through a smaller hole to make a thinner wire. The tool with the small hole would be a die. 2. You might be referring to wire EDM (Electrical Discharge Machining). This is a way of cutting metal with electricity. It is often used in the fabrication of dies because it can cut through the hardest metal - metal that is too hard to cut with normal cutting tools.
what is the purpose of edm
YES ! It is actually possible to die of boredom. GET OUT NOW BEFORE IT'S TOO LATE !
I believe nothing would happen to you until the salts and dirt from your hand contaminates the water making it conductive. I wouldn't want to test it and i wouldn't encourage you to. and i don't know what a edm is.
in wire cut, a wire is passed through a metal or is placed next to it. the wire works as one of the electrodes while the work piece would be the other one; using andielectric liquid to isolate the wire from the work piece. the electricity is conducted in the wire. as the wire gets closer to the work piece the electricity (electrons) tend to jump from the wire to the work piece in order to create a complete electrical circuit that's when a spark is formed. the dielectric helps us by isolating the wire from the work piece as long as it can, so we can have enough difference in potential between two electrodes before the spark is formed, it works like capacitor stopping the current from going through it until it collapses at a potential and enough current passes through at once. A collateral effect of this passage of current is that material is removed from both the electrodes.

edm.
EDM electrodes consist of highly conductive and/or arc erosion-resistant materials such as graphite or copper. EDM is an acronym for electrical discharge machining, a process that uses a controlled electrical spark to erode metal.
