Electrical discharge machining (EDM) is a process of removing material by exposing it to repetitive controlled electrical discharges. It is suitable for thermoelectric phenomena. When a discharge occurs between the electrode/wire and the workpiece, heat energy is generated on the workpiece. This leads to the removal of the material layer.
EDM can be used to machine difficult geometries in small batches or even on job-shop basis. Work material to be machined by EDM has to be electrically conductive. 2.

EDM or Electrical Discharge Machining, is a non-traditional machining method primarily used for cutting complex or odd shapes in hardened metals or materials that would be impossible to cut with traditional machining methods. The main limitation of Electrical Discharge Machining is that it can only cut materials that are electrically conductive.
Electric Discharge Grinding (EDG) follows the same principle of material removal (i.e. melting and vaporization) but the construction resembles the conventional grinding process. Instead of a stationary form electrode as used in EDM, a wheel electrode made of conductive material is …
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). 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 sparks produced by the sinking EDM process-500 to 30,000 sparks per second, seem to occur at the same time. In fact, these rapid sparks are produced once at a time. Obviously, the EDM process is not too normal for us to perceive. Although our opinions betray us, it is still important to understand this fact to properly control the EDM process.
Wire EDM and Hole Popping With these specialty techniques, Metal Craft accurately produces delicate parts and machines extremely hard materials. They're also excellent for making high-tolerance pieces and complex shapes. Our wire EDM process uses a charged wire to cut through conductive materials using the heat produced by electrical sparks.
Electrical discharge machining is a quick and unique way to create accurate deep small holes drilling in materials, regardless of their hardness. The hole drilling process involves using a brass electrode tube to channel the electrical discharges onto the material. This helps to create holes of various small dimensions.
Unless there is a high amount of material removal necessary, grinding is a faster machining process than EDM. On the other hand, if there is a large amount of material to be removed to achieve the desired shape, using EDM to machine the part before the grinding process is more efficient.
To improve the material removal rate (MRR), the effects of electrode rotational speed, gap voltage and pulse width on the MRR of PCD EDM grinding process were studied. By adding pre-experiments, the optimization process is more rapid. A second-order regression model of MRR is established by using response surface method based on Composite Circumscribed design (CCC).
