This is how an electro-discharge machine looks like. 2.2 Wire EDM Figure 2.2: Wire Electrical Discharge Machining Wire-cut EDM (WEDM) fig.2 is one of the most favorable variants owing to its ability to machine conductive, exotic and high strength and temperature resistive (HSTR) materials with the scope of generating intricate shapes and profiles. Background: Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for very hard materials without using high cost of cutting tools. It was first observed in 1770 by Joseph Priestley. Download and Read online Electrical Discharge Machining ebooks in PDF, epub, Tuebl Mobi, Kindle Book. WHEN TO USE EDM Where deep cutting is required In unattended cutting For high-expertise parts Where EDM finish is specified For hard materials For sharp inside corners For the most complex geometry. Wire Electrical Discharge Machining (WEDM) is an electrothermal non-traditional machining process used for machining electrically conductive materials that are difficult to machine. K.P et al., has studied the wire electric discharge machining of Ti-6Al-4V titanium alloy with a bundled electrode [6]. The cutting tools are electric sparks, which have been set up and controlled with the help of a generator. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes. 2.2 Wire EDM Figure 2.2: Wire Electrical Discharge Machining Wire-cut EDM (WEDM) fig.2 is one of the most favorable variants owing to its ability to machine conductive, exotic and high strength and temperature resistive (HSTR) materials with the scope of generating intricate shapes and profiles. Abstract: Wire electric discharge machining (WEDM) is a widely accepted non-traditional material removal process for manufacturing of components with intricate shapes. Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). Electrical Discharge Machining is also called or known as Spark machining, spark eroding, burning, die sinking, wire burning or wire erosion. 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). The strokes of the X, Y, and Z axes are 200 mm, 100 mm, and 100 mm, respectively. v����Z�-"�� Wire electrical discharge machining process has been established as a crucial non-conventional thermoelectric machining technique to machine the materials which are a conductor of electricity. /F4 15 0 R Electrical Discharge Machining Fundamental Manufacturing Processes Video Series Study Guide - 1 - Training Objectives After watching the video and reviewing this printed material, the viewer will gain knowledge and understanding of electrical discharge machining, or EDM, principles and capabilities. Wire–electrical discharge machining is a form of EDM in the category of non–traditional machining process. The present invention provides an electrical discharge machining apparatus capable of reducing kerf loss and realizing highly accurate and efficient slicing. The high-pressure EDM is mainly used to machine difficult-to-machine materials and high strength /Resources << Wire Electrical Discharge Machining Traveling Workpiece Wire Electrode Motions Wire Motions Wire EDM Used Primarily for Through Hole Machining. Generally, wire-cut electrical discharge machining is used for turning because it is not concerned with electrode tooling cost. /Parent 2 0 R Wire electrical discharge machining (WEDM) has grown tremendously in recent years. These made the micro wire EDM an important manufacturing process to meet the demands. Keywords: wire electrical discharge machining (WEDM), Ti6Al4V alloy, process performance, surface integrity. This process has brought dramatic improvements to industry in accuracy, quality, productivity, and earnings.

The wire moves in a carefully controlled pattern, roughly analogous to a woodworker’s scroll saw, causing sparking to occur between the wire and the workpiece. Image credit: Pixel B/Shutterstock.com. The uses for wire electrical discharge machining have expanded – as wire erosion as a machining technology has improved, and high volume wire EDM machining has increased it’s capabilities.
