Abstract: A new high frequency short pulse electrochemical machining(HSPECM) set-up was developed, including mechanical machine set-up, pulse power, drive system, interelectrode gap detection unit and controlling system. According to the present investigation, using a group of optimal parameters, an experiment replicating complex shape workpiece was made. From the photograph of the machined jobs, it can be seen that it has clear contour and smooth end surface. And the machining rate increases largely and the effective utilization of HSPECM in the micromachining field will be further strengthened.
