中文摘要：
微小孔在航空航天领域有广泛应用,而微细电化学加工是一种比较理想的微小孔方法。对工具阴极高速旋转条件下,工具阴极表面形成具有一定绝缘效果气泡层的现象进行了研究。分析了工具阴极旋转速度对微小孔电化学加工时半径过切值和杂散腐蚀的影响。结果表明,采用高旋转速度有利于减小微小孔电化学加工时半径过切值、表面粗糙度值和杂散腐蚀,对微小孔的加工精度提高起到了重要作用。
英文摘要：
The metal parts with small holes are widely used in the fields of aeronautics and astronautics. micro-electro chemical machining （micro-ECM） provides a viable alternative for drilling micro/small holes on metal parts with acceptable quality. This paper discusses the phenomenon of gas film formation of a certain insulation effects on the cathode,because of the cathode high speed rotating. Effects of several process factors,such as the cathode rotating speed on the radial of overcut,value of surface roughness and stray corrosion are investigated. The results show possibilities of improving the machining accuracy by utilizing cathode higher speed rotating.
