Determination of Machining Parameters in Spheroidal Graphite (SG) Cast Iron

Spheroidal Graphite Cast iron is a high carbon containing, iron based alloy, in which the graphite is present in spherical shapes. As Spheroidal graphite cast iron, sometimes referred as ductile iron, constitutes a family of cast irons in which the graphite is present in a spheroidal form. The graphite nodules are small and constitute only small areas of weakness in steel like matrix. Spheroidal Graphite Cast iron is one of the most important materials in automobile industry. Its ductility property will useful to make many components in various industrial applications. In this project machining characteristics of Various SG iron Specimens using Wire Electrical Discharge Machining (WEDM) process is studied. Following experimental procedure is conducted. First SG Iron castings with different composition will be manufactured. Then all these casting specimens will be machined under EDM process.
