A process called “WEDM” or “wire electrical discharge machining” enables manufacturers to machine complex parts from materials which often do not permit machining using other techniques. Conventional EDM cannot produce narrower angles or more complex patterns, while wire-cut EDM can be performed. The size of this radius is determined by the wire diameter plus the spark gap. Numerous tiny holes appears due to erosion of impulse discharging, and therefore get the needed shape of workpiece( as show in figure 1-1). A thin, electrically charged EDM wire held between upper and lower mechanical guides forms one electrode, while the material being cut forms the second electrode. The second type of electrical discharge machining is called wire EDM and is also known as wire erosion, wire burning or spark EDM. That’s because wire EDM machines can cut any spur gear, and the accuracy is on point! EDM comes in two basic types: wire and probe (die sinker). The various features of wire-cut EDM process are: (1) Forming electrode adapted to product shape is not required: Since a thin wire of copper or tungsten is used as the electrode to machine the workpiece as programmed, there is no need for forming electrodes which are traditionally made by cutting and grinding an expensive alloy of silver and tungsten or copper and tungsten. Understanding the Wire EDM Process 83 When the wire turns a corner, it can produce a sharp edge on the outside corner, but it will always leave a small radius on the inside corner, as demonstrated in Figure 5:4. The water acts as a coolant and flushes away the eroded metal particles. A constant gap is always maintain between the wire and w/p. Wire EDM Fundamentals Revolutionizing Machining Wire Electrical Discharge Machining (EDM) is one of the greatest innovations affecting the tooling and machining industry. Wire EDM can cut diameters ranging from a few thousandths of an inch to several inches, to lengths from 0.5” (12 mm) to 18.0” (450 mm) and with high dimensional accuracy. Wire EDM is commonly used … This process has brought dramatic improvements to industry in accuracy, quality, productivity, and earnings. High frequency pulses of alternating or direct current is The wire-cut EDM machine is operated by a CNC control instrument that can control the wire on a three-dimensional axis for greater flexibility. CNC wire cut EDM machine puts impulse voltage between electrode wire and workpiece through impulse source, controlled by servo system, to get a certain gap, and realize impulse discharging in the working liquid between electrode wire and workpiece. Because the wire is so fine, you can cut small-radius inside corners or even narrow slots. Introduction EDM Process Wire Cut EDM Process Advantages Disadvantages Applications Introduction 3.
