摘要：
This work investigates the influence of tool surface area (TSA) on the average surface roughness (Ra), tool wear rate (TWR) and material removal rate (MRR) in the micro-electrical discharge machining (mu EDM). The effects of three different TSAs were investigated at three different discharge energy settings. It was observed that the TSA had substantial influence on mu EDM performance owing to scaling effect. Therefore, the low-frequency workpiece vibration was applied to improve the mu EDM performance. The surface topography of machined surfaces was examined using scanning electron microscopy to disclose the effect of TSA as well as vibration frequency on mu EDMed surfaces.
