为了研究加工参数对微细电火花加工表面形貌的影响，首先从理论上分析了影响形貌的主要因素。然后在多功能微型非传统机床和不同参数的RC脉冲电源组成的微细电火花加工系统上进行了实验。拍摄加工样品的SEM照片，并根据这些照片比较不同参数下加工的表面形貌。结论是随着电压和电容的增加，放电坑会增大。当单脉冲能量相同而电压和电容的组合不同时，实验结果表明，放电坑的大小取决于单脉冲能量，这与理论分析相符。对不同电压下加工的表面平整度进行了测量和分析。
In order to study the influence of the processing parameters on the topography of the surface machined by micro-EDM, the main factors that affect the topography are first analysed theoretically. Then the experiment is carried out on the micro-EDM system composed of multifunctional micro non-traditional machine tool and RC pulse power supply with different parameters. The SEM photos of machined samples are taken, and according to these photos, the topographies of the surface machined in different parameters are compared. The conclusion is that the discharge craters will ascend with the increase of the voltage and capacitance. When the single pulse energy is same but the combinations of the voltage and capacitance are different, the experimental result shows that the size of the discharge craters depends on the single pulse energy, which is coincident with the theoretical analysis. The plainness of the surface machined with different voltage is measured and analysed.
