electrochemical forming process. The noteworthy feature of electrolysis is that electrical energy is used to produce a chemical reaction, therefore, the machining process based on this principle is known as Electrochemical machining (ECM). This process works on the principle of of Faraday's laws of electrolysis.

Back End(BE) Process Wafer Back Grinding • The typical wafer supplied from 'wafer fab' is 600 to 750μm thick. • Wafer thinned down to the required thickness, 50um to 75um, by abrasive grinding wheel. › 1st step : Use a large grit to coarsely grind the wafer and remove the bulk of the excess wafer thickness.

predictable, making it much easier to quote, EDM leaves a totally random pattern on the surface as compared to tooling marks left by milling cutters and grinding wheels. The EDM process leaves no residual burrs on the workpiece, which reduces or eliminates the need for subsequent finishing operations.

As many as 50 hours of machining can be performed with one reel of wire, which is then discarded. f Wire EDM (a) (b) (a) Cutting a thick plate with wire EDM.

Characteristics of EDM (a) The process can be used to machine any work material if it is electrically conductive (b) Material removal depends on mainly thermal properties of the work material rather than its strength, hardness etc (c) In EDM there is a physical tool and geometry of the tool is the positive impression of the hole or geometric ...

Electrical Discharge Machines (EDM) Wire EDM machines utilize a very thin wire (.0008 to .012 in.) as an electrode. The wire is stretched between diamond guides and carbide that conduct current to the wire and cuts the part like a band saw. Material is removed by the erosion caused by a spark that moves horizontally with the wire.

The systems engineering process is the heart of systems engineering management. Its purpose is to provide a structured but flexible process that transforms requirements into specifications, archi-tectures, and configuration baselines. The disci-pline of this process provides the control and trace-ability to develop solutions that meet customer ...

Application of EDM The EDM process has the ability to machine hard, difficult-to-machine materials. Parts with complex, precise and irregular shapes for forging, press tools, extrusion dies, difficult internal shapes for aerospace and medical applications can be made by EDM process. Some of the shapes made by EDM process are shown in Figure 3.
