Abstract

In spite of huge advancement in machining process and much promising surface integrity, die-sinking EDM process is unavoidable. Micro-crack formation in the white layer zone in EDM leads to damage the quality of machined surface. This paper furnishes a quantitative investigation of micro-crack formation, in terms of crack width and orientation of micro-cracks formed in the white layer zone. The impact of processing conditions like peak current (Ip) and pulse on duration (Ton) on crack formation is examined by utilizing the perceptions of scanning electron microscope (SEM). In this work, micro-hardness is measured at different zones that are deposited layer, heat-affected zone (HAZ) and base metal. It is observed that significant improvement in the hardness value of the recast layer (9.175 Gpa) as compared to base metal (3.115 Gpa) of M2 die steel.
