Electric discharge machining (EDM) is a non conventional machining method to fabricate very tough and hard materials. Although EDM has played a vital role in machining industry but with advancement of technology, alternative advanced methods of machining have been evolved such as near dry EDM (ND-EDM) and powder mixed near dry EDM (PMND-EDM). These technologies have been proven more efficient than traditional EDM in terms of machining performance characteristics such as higher material removal rate (MRR), better surface finish (Ra) and low tool wear rate (TWR) with high tolerance quality products. In this study an approach has been made to draw experimental comparison between ND-EDM and PMND-EDM in terms of MRR, SR and TWR. The experimental result and analysis revealed that PMND-EDM was better machining method than ND-EDM as in the former technique, the M RR increased by 45.04 % while SR and TWR reduced by 45.33 % and 60.60% respectively

Abstract 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.

Edm Process

Electrical Discharge Machining is a thermo-electric process and one of the advanced methods of machining. Most publications on the EDM process are directed towards non-rotational tools, but rotation of the tool provides a good flushing in the machining zone. In this study, the optimal setting of the process parameters on Rotary Electric Discharge machining (REDM) was determined. The important process parameters that have been selected are peak current, pulse on time, pulse off time and rotational speed of tool with output response as Material Removal Rate (MRR).Taguchi experimental design (L27 orthogonal array) was used to formulate the experimental layout and experiments were conducted on Hardened stainless steel machined with copper tungsten electrode. ANOVA method was used with the help of MINITAB 17 software to analysis the influence of input process parameters on the MRR using Rotary Electric Discharge Machining. The input parameters were optimized in order to obtain maximum MRR, The results of the present work revealed that proper selection of input parameters will play a significant role on MRR.
