Electronic magnetic Forming (EMF) Dept Of Mechanical Engg Final Year Project

Electronic Magnetic Forming (EMF) is a process to use electromagnetic forces to produce metal without using a tool or punch that come into contact with the part.  This is also an ideal process for joining mechanically or assembling metal components.  An electromagnetic coil is driven by an electric current in a sharp pulse to generate the force for metal forming.  The product produced by this method is free from toll marks and heat effects since there is no tool or abnormal heat.

 The process is suited best to form techniques on aluminum leave wrinkles on the job like spring back and poor reproducibility. Therefore, EMF process is a potential application in automobile to form sheet metal components.

  The line voltage supply charge the capacitors and the whole circuit is separated from the power source.  The charge stored in the capacitors flows like current through the work coil when the forming circuit switch gets closed. The current forms a strong magnetic field between the coil and the work piece which is called Lenze’s law. EMF is used to attach and assemble components.

 The main components of the machine are The structure, The Die, Hydraulic power-pack and hydraulic circuit, Machine Control Circuit, Electromagnetic coil with accessories, Capacitor, Voltage multiplier circuit for capacitor charging, Capacitor charging circuit, and Capacitor Discharging circuit.

 Conclusion:

 This Electronic Magnetic Forming (EMF) project concludes excellent technique for forming thin metals, good for mechanically joining metals or non-metals. It is quicker, easier, and easy to implement. It is easily automated and product formed is free from any defects and likely rapid growth of EMF machines.
