Abstract:The TWR for the pure copper electrode was 0.514 gm/min, while the composite electrode (Cu-1%Cr-0.5%WC-1%Ag) had the lowest TWR at 0.215gm/min.• The pure copper electrode had a higher MRR of 54.5588 mm 3 /min, while the composite electrode (Cu-1%Cr-0.5%WC-1%Ag) had the best MRR at 56.8689 mm 3 /min. • The composite electrode (Cu-1%Cr-0.5%WC-1%Ag) had an improved SR of 3.747 μm versus 3.967 μm for the pure copper electrode. • Current, followed by pulse on/off time, significantly impacted the electrodes' TWR, MRR… Show more
“…A very high elevated temperature (8000 to 12000 ℃) generated in the machining gap due to the electrical discharge results in the melting and vaporizing of the machined material; material removal happens [3]. Different medical, aerospace, and automotive industries have widely adopted EDM to produce high-precision elements and parts [4]. Several techniques have been developed to improve this important process, including adding powders to the used insulating fluid called powder mixed electrical discharge machining (PMEDM).…”
