This paper investigates the relationship between bubble behavior and material removal volume in electrical discharge machining. Metal rod and plastic flat plate with metal wire inserts are used for electrodes, and bubble expansion and contraction caused by a single pulse discharge, as well as flying debris, is observed using a high-speed video camera. Material removal volume is obtained by integrating the surface profile curves of the discharge crater measured by using surface roughness measuring instrument. It is found that debris are scattered from the discharge point during discharge duration and while bubble is expanding. It is also found that maximum bubble diameter and bubble expansion speed do not affect the material removal volume.
