Study on Micro-Topography Characteristics of EDM Surface

Abstract:

This paper is based on the experimental observation. The micro-topography characteristics of electrical discharge machining (EDM) surface were studied. The results show that the EDM surface is made up of three-dimensional craters and hard protrusions overlapped alternately which distribute randomly and non-directionally. The pulse energy has significant effect on the forming of EDM surface profiles, and peak current and pulse width are the main factors.
