Abstract
In wire EDM, better exclusion of debris from the machined kerf is very important to obtain a stable
machining performance. The purpose of this study is to investigate the fluid flowin the kerf and better jet
flushing conditions of working fluid from the nozzles. The flow field and the debris motion in the kerf
were analyzed by computational fluid dynamics (CFD) simulation, comparing with the observation by
high-speed video camera. The influence of flow rate of working fluid from nozzles and the nozzle standoff
distance on flow field in the kerf and debris particle motion were discussed.
