In today's highly competitive world, it is essential to understand the electrical discharge machining (EDM) processes. Every manufacturer needs to learn and understand the many advantages of EDM. We will be examining the three basic EDM processes: wire EDM, ram EDM, and small hole EDM drilling. See Figure 1:1. Figure 1:1. The Three EDM Processes.

Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining process. Electrical energy is used to generate an electrical spark, and material removal mainly occurs due to the thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high-strength temperature-resistant alloys.

Wire Electrical Discharge Machining (EDM) is one of the greatest innovations affecting the tooling and machining industry. This process has brought dramatic improvements to industry in accuracy, quality, productivity, and earnings. Figure 2:1 shows various wire EDM machines. 2 .

Electric discharge machining (EDM), sometimes colloquially also referred to as spark machining, spark eroding, burning, die sinking or wire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks).

Micro-EDM – capable of not only micro-holes and micro shafts as small as 5 m in diameter but also complex 3D micro cavities. Unlike conventional EDM, the workpiece in WEDM is almost never submerged in dielectric fluid. Instead, a localized stream is used. 1. No wear EDM : work to electrode wear ratio of 100 or more.

The EDM process uses heat from electrical sparks to cut the material. The sparks create a heat-affected zone that contains a thin layer of recast, also called “white
