摘　　要：对双向走丝的电火花线切割提出一种非对称的切割方法,根据走丝方向,线切割机床采用不同的放电脉冲参数来加工工件。设计了实现该方法的可编程高频电源。实际使用表明:该电源能在不降低加工精度的同时,较大幅度地提高线切割加工速度。A method of asymmetric WEDM for two-way wire movement cut has been proposed. According to the direction of wire movement, the workpiece would be processed by EDM with different pulses parameters. For this purpose, the programmable high-frequency power supply was designed. Actual use shows that the line cutting speed will be greatly improved by the power supply, but not reduced the precision at the same time.
