The Study of the effect of input parameters on output characteristics in the EDM process

In this study the effect of input parameters of the EDM process including pulse on- time، pulse current and voltage on the output characteristics (material removal rate، tool wear ratio and surface roughness) in the machining AISI D6 tool steel has been studied. This study shows that increasing the pulse on time، material removal rate and the surface roughness are increased and the tool wear ratio is reduced. Also، based on obtained results by increasing pulse current، material removal rate، tool wear ratio and surface roughness are increased.
