Abstract
This paper presents the machining of the nickel sheet using The micro-EDM process. The effect of machining parameters such as pulse on time and gap voltage on the surface integrity parameters such as recast layer thickness, heat affected zone, change in micro-hardness of the workpiece surface and metallurgical transformation in the machined samples has been reported. It is found that ultrasonic vibration given to the workpiece, results in a reduction in the thickness of the recast layer and varies from 7 to 22 µm. The hardness of the fabricated micro-holes improves significantly on the introduction of ultrasonic vibration to the workpiece and was in the range of 116–141HV. In this study, heat-affected zone was not observed in optical as well as in SEM images. The result of the EDS analysis shows that less amount of the residuals of the carbon and oxygen were present over the fabricated holes.
