主动匹配式micro-EDM脉冲电源设计与实验
Design and experiment of active matching micro-EDM pulse power supply
摘要
Abstract
For the purpose of increasing the efficiency of micro electron discharge machining ( micro⁃EDM) , an ac⁃tive matching micro⁃EDM pulse power supply is designed. Using the active matching pulse generation circuit, the pulse parameters can be matched automatically depending on the charge and discharge of the polar capacitor. The machining efficiency, quality and low voltage machining property were analyzed through experiments. The result shows that the pulse supply can accomplish a single charge and discharge in one pulse cycle. Compared with regular transistor pulse generator, this power supply can improve material remove rate and machining quality, the sizes of pits are almost the same, with no metasomatile deposit. The pulse supply can work in 24V low voltage charge, with high roundness and precision of the machined micro⁃hole. This power supply can enhance the efficiency of micro⁃EDM machining and guarantee a high machining quality.关键词
