| 摘 要： | 超短脉冲微细电解加工时,极间加工间隙很小,加工过程的稳定性是影响加工精度的重要因素。在所建立的加工控制系统中,采用两步短路对刀法精确定位电极初始间隙,利用霍尔电流传感器实时检测平均加工电流,动态控制电极的进给运动速度,从而保持不同加工条件下稳定加工的最小加工间隙。进行了微细结构的电解加工试验,通过检测加工过程的状态,保证了加工的稳定性,实现了线宽只有25μm的微细结构加工。

| Abstract: | While an ultra-short pulse power supply was applied into the electrochemical micro-machining,the stabilization of machining process is an important factor affecting the machining precision due to the very small inter-electrode gap.In the machining control system,a two-step location method was proposed to exectly define the beginning iner-electrode gap.A Hall current sensor was used to detect the average current signal in real-time,and the feed speed was controlled dynamically.Therefor the smallest machining... |
