Evaluation of Material Removal Rate on Various Electrodes for Stainless Steel 316 Material on Die-Sinking EDM by Using Taguchi Technique

The creation of novel materials has grown tremendously, but the main issue is that they are exceedingly challenging to manufacture. So, it is essential to implement certain new machining techniques. Due to its capacity to create detailed, complex forms and to work with hard materials, (EDM) is a nontraditional and widely used machining technique to make machine dies, machine punches, and various press tools.

Copper, brass, and graphite were employed as the three distinct electrode materials in the experiment along with dielectric fluid.L9 orthogonal array has been selected using the taguchi technique, and three levels are taken for each of the variables. The set of tests that were planned in an orthogonal array have been carried out. Experimental results were examined analytically and visuallyThe optimal values of MRR were calculated. Experimental findings revealed that, brass electrodes with greater surface polish had lower current values (18 A) and longer pulse-on periods (65 S) than copper electrodes with the highest MRR (30 A) and pulse-on values (50 S).
