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 (μEDM). The effects of three different TSAs were investigated at three different discharge energy settings. It was observed that the TSA had substantial influence on μEDM performance owing to scaling effect. Therefore, the low-frequency workpiece vibration was applied to improve the μEDM 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 μEDMed surfaces.

刀具表面积和工件振动对 μEDM 性能的影响

这项工作研究了刀具表面积 (TSA) 对平均表面粗糙度的影响 (R一种), 微放电加工中的刀具磨损率 (TWR) 和材料去除率 (MRR) (μ电火花加工）。在三种不同的放电能量设置下研究了三种不同 TSA 的效果。据观察，TSA 对μEDM 性能归因于缩放效应。因此，应用低频工件振动来改善μ电火花性能。使用扫描电子显微镜检查加工表面的表面形貌，以揭示 TSA 以及振动频率对μ电火花加工表面。
