EDM or Electrical Discharge Machining is a process by which metal is removed by electrical energy. A spark is discharged from an electrode vaporizing the metal. In really EDM is a very precise method of machining and is used when a metal is too hard or tough to machine conventionally. The experimental study presented in this paper aims to select the most suitable cutting and offset parameter combination for the wire electrical discharge machining process in order to get the desired surface roughness value, dimensional and corner cutting accuracy for the machined workpieces. A series of experiments have been performed on two types of steel material with same thicknesses. The test specimens have been cut by using different cutting and offset parameter combinations of the “Mitsubishi RA90” wire electrical discharge machine in the University Technical Malaysia Melaka CNC center lab. The surface roughness of the test pieces has been measured by using a surface roughness measuring device. The dimension accuracy will be measured by optical comparator and digital caliper. For accuracy of sharp corner cutting image analyzer will be used. The related tables and charts have been prepared for material type, wire diameter and wire type. The tables and charts can be practically used for EDM parameter selection for the desired workpiece.
