Study on MRR, TWR in AISI 316 by EDM Machine using Copper Electrode

The current project is doing exploratory research of EDM on AISI 316 with copper metal as the electrode. Small tubular electrodes areconstructed of copper. Copper is substantially easier to process, yet it does not wear as quickly as tungsten. Because new materials areinjected continuously throughout the EDM machining process, EDM electrodes do not need to be resistant to wear or arc erosion. Theseaccept current, pulse on time, and pulse off time as input parameters. The experiments used fixed parameters such as gap voltage,dielectric, and cutting depth.The observations of material removal rate, tool wear rate, and surface roughness are used to quantify EDMoccurrence. Evaluate the impact of process parameters on response variables (MRR, TWR) using the L9 Taguchi orthogonal matrix.
