Abstract
The paper briefly deals with the surface characteristic behavior of EMD-eroded surface utilizing scanning electron microscope, metallography, and stylus profilometer. The increment in pulse duration - one of the many influencing parameters, results not only in the increase of surface roughness but also in the increment of depths of cracks. It is suggested that the discharge time for the application of fine cutting conditions to improve the surface characteristics should not be estimated on the basis of surface geometry improvement only because the removal of white layer and heat-affected zone including cracks requires considerable discharge time. It is shown how the newly developed approach of Data Dependent System can be applied to the profiles of random EDM surfaces and a better analysis of the surface can be made.
