Wire edm is a non traditional machining operation in which complicated profiles are cut by the help of a wire by the application of heat produced from the electrical sparks.
Wire cut edm process pdf.
The wire is usually made of brass or stratified copper and is between 0 1 and 0 3 mm diameter.
It is probably the most exciting and diversified machine tool developed for this industry in the last fifty years and has numerous advantages to offer.
Because of its versatility manufacturers use edm wire cutting machine operation for an extensive range of applications.
When cutting carbide on certain wire edm machines the initial first cut can cause surface micro cracks.
Figure 2 1 shows various wire edm machines.
When precision carbide parts are needed then skim cuts are used.

To eliminate them skim cuts are used.
In wire edm thin single strand wire is used to cut the material from the workpiece.
Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm.
It was introduced in the late 1960s and has revolutionized the tool and die mold and metalworking industries.
A constant gap is always maintain between the wire and w p.
Some older wire edm machines used capacitors.
Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes separated by a dielectric liquid and subject.
The wire is continuously fed through the workpiece submerged in a tank with dielectric medium.
Wire edm wire edm vertical edm s kid brother is not the new kid on the block.
Wire cut edm applications.
Wire edm fundamentals revolutionizing machining wire electrical discharge machining edm is one of the greatest innovations affecting the tooling and machining industry.
Electrical discharge machining edm also known as spark machining spark eroding die sinking wire burning or wire erosion is a metal fabrication process whereby a desired shape is obtained by using electrical discharges sparks.
Contact between the electrode and work piece.
The wire is usually made of brass.
Wire electrical discharge machining wedm uses a metallic wire to cut or shape a workpiece often a conductive material with a thin electrode wire that follows a precisely programmed path.
Ultrasonic machining process usm ultrasonic machine and its process parameters.
Because the process can cut very small pieces it is often an ideal choice for the production of small highly detailed items that would normally be too delicate for other machining options.
This process has brought dramatic improvements to industry in accuracy quality productivity and earnings.
