This objective of research was to study the optimization of P20-steel taper cutting with WEDM by statistical applicability methodology. The parameters were taper angle, pulse-off time and arc-off time. The response value of statistical analysis was surface roughness average (Ra). Summary, the research optimization of P20-steel taper cutting with WEDM were the arc-off time of 14 µs, pulse-off time of 50 µs and taper angle of 10.</p> ER -
