The electric discharge machining is a non-conventional machining process, in which the spark is electric spark is generate in gap between the work piece and electrode. Due to heat generated by spark in between the workpiece and electrode, the material get vaporized from small area form workpiece and get cool down with the help of dielectric fluid. In present study low carbon mold steel use as a work piece and copper electrode is used. The electromagnetic field included in the process to analyze the effect of the input parameters on the machine response parameters like MRR and the surface roughness value (Ra). The study is done on EDM process with and without EMF by varying the input parameters Ton (μs) and keeping the other parameters constant (Toff (μs), Current (A) & Voltage (V)). The set of the neodymium magnets are used in the set up having 4500 gauss units. The circular plate is designed to hold the neodymium magnets nearer to the work piece using CATIA V5 version. 3D printer is used to fabricate the circular plate that holds the electromagnets precisely near to the area under spark to have a maximum effect of EMF in the EDM process. The experimentations shows that response parameter shows good output at pulse on time of 200 ms and 300 ms with and without EMF respectively.
