Abstract

The importance of surface integrity of electric discharge machined components has been recognized by the industry and it is still continues to be the major concern among the researchers. This paper presents a study of the relationship between EDM input parameters (DUTY CYCLE, PULSE-ON TIME and TOOL POLARITY) and surface integrity. This study shows that, in both cases of TOOL POLARITY (positive and negative), with increasing pulse on-time and DUTY CYCLE, the rate of HARDNESS decline in the layers near the machined surfaces is augmented and the depth of the heat effected zone is increased, Also In the negative polarity the amount of HARDNESS decline and depth of the heat effected zone is low. According to the results of the EDX analysis, in the positive polarity, the rate of penetration and carbon diffusion is higher than the negative polarity.
