摘要：

Low machining accuracy has been a technical bottleneck for the application and promotion of electrochemical machining (ECM). Since the 1990s, it has been recognized by scholars that high-frequency pulsed power supply can improve the precision of ECM. But, in terms of the experimental results of our study, a new discovery was found that the increasing of the frequency has no effect on improving the machining accuracy of ECM. Comparing with the DC power supply, the experiment results show that the machining accuracy under pulsed power supply is decided by effective average voltage value, regardless of the frequency of the pulsed waveform, the duty cycle, and the pulse peak.
