The various functions of EDM machining are:
Material Removal: EDM removes material from the workpiece by creating sparks or electrical discharges that erode the material, making it useful for cutting, shaping, and machining hard materials that are difficult to work with using conventional methods.
Precision Machining: EDM can achieve high levels of precision, making it suitable for manufacturing intricate and complex shapes with tight tolerances.
No Contact Cutting: Unlike traditional machining methods, EDM does not involve direct contact between the tool and the workpiece, reducing the risk of tool wear and enabling the machining of fragile or delicate materials.
Versatile: EDM is effective for a wide range of materials, including metals, ceramics, and even conductive non-metals, making it a versatile machining process.
Wire EDM: Wire EDM is a variation of EDM that uses a thin wire as an electrode to cut complex shapes with extremely tight tolerances. It's especially useful for making dies and moulds.
Small Hole Drilling: EDM can create small, precise holes in materials that may be difficult to achieve through traditional drilling methods.
Heat-Treated Materials: EDM can machine heat-treated materials, maintaining their hardness and structural integrity, which can be challenging for other machining processes.
Tool and Die Making: EDM is commonly used in tool and die manufacturing for producing moulds, dies, and other precision components used in various industries.
Low Tool Wear: The tool electrode in EDM experiences minimal wear, allowing for extended tool life and reduced tool replacement costs.
Complex Contours: It is capable of producing intricate and irregular shapes that are often challenging to achieve using conventional cutting tools.
