| Abstract: | The broken wire of WEDM-HS tool electrode has always been an important factor that influences machining efficiency of WEDM-HS.This paper addresses the control pulse currents as the its objective,having designed a ladder-like high and low composite pulse power which is low-abrasive to the tool electrodes and an AVR microcontroller-based visualized control system.Test result shows that in the same processing efficiency,the pulse power can reduce the impact and loss to the tool electrode to some extent. |
