摘要
为了解决加工间隙内电解加工产物的排除问题,在分析电解线切割加工特点的基础上,采用环形镀锌黄铜丝作为阴极,在电机的驱动下,使环形丝的运动方向与重力方向保持一致,从而便于带出加工区的电解产物;在搭建的加工系统上进行了正交试验,研究加工电压、进给速度、电解液浓度及环形丝单向运丝速度对加工间隙的影响。最后采用优化的加工参数加工出缝宽为250μm、深宽比达20的五角星结构。
The electrolysis products in the gap always affected the WECM precision, a ring wire travelling in one direction during the process was proposed to enhance the efficiency of removing prod- ucts,and the wire tension was controlled in constant to ensure the stability of wire travelling. The in- fluence of several processing factors, such as wire travel speed, feed speed, concentration of electrolyte and voltage, on the machining process was investigated. Structures with high--aspect--ratio were fab- ricated,the width of the slits was 250μm and the aspect ratio of the slits was nearly 20.
