EBM Diagram : electron beam machining diagram Working of EBM : When the high voltage DC source is given to the electron gun, tungsten filament wire gets heated and the temperature raises up to 2500°C. Now customize the name of a clipboard to store your clips. They take different power supplies, that are not interchangeable. Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process where a thin single strand metal wire, along with de-ionised water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks, while preventing rust. Metal forming using deep drawing has its advantages and disadvantages. SUS304 Stainless Steel vs SS304: What’s the Difference? View All. The spark generated by this process produces heat, which remove metal by erosion and evaporation.

Wire EDM tooling and workholding should be practical, reliable, as well as aimed towards the main goal of problem solving. If you Google "EDM thesis", there is a lot of information out there. 2010. The Wire transport system, Wire guides, automatic wire threader and dielectric systems are critical to the productivity of a Wire EDM machine. The discharge causes the melting, and probably the vaporisation, of a minute piece of material, slowly eating into the work piece. The process can be as simple as using a small diameter metal tube to cut a precise hole in a metal block to using a carved graphite block to machine a toy shape in a metal block for injection molding. 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). Wire Electric Discharge machining WEDM INTRODUCTION Wire EDM Machining (also known as Spark EDM) is a unique adoption of EDM; it is an electro thermal production process similar in configuration to band sawing, in which a thin metal wire acts as a saw in conjunction with deionized fluid, used to conduct electricity, is used to cut through metal by means of heat from electrical sparks. 20 Best Paying Jobs in Energy, SolidWorks Lofted Boss/Base: Creating Lofted Features in Solidworks, How 2020 Has Changed Mechanical Engineering.

Alternative Machine Tool, the choice for machine shops. high quality surface finish or high precision, Is Energy a Good Career? A spark is sent from the shortest distance between a single strand of wire, usually brass, and the workpiece where it jumps the gap (known as the spark gap) at which point material is burned away from the workpiece. 8 Pages. Join our mailing list to get regular updates. Here the tool is negative and w/p is positive. For Inquiries or Questions… Contact Us. Wire EDM is used primarily for shapes cut shapes through a selected part or assembly. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. To achieve a high quality surface finish or high precision, it is necessary to perform successive lower power “skims” which gradually remove less material on each cut. SLQ. 6 Pages.
