Study on jet flushing method for improving debris exclusion in wire EDM

open access: yesNihon Kikai Gakkai ronbunshu, 2019
In wire electrical discharge machining (wire EDM), debris tends to stagnate around the wire electrode, since the machined kerf is very narrow. Then, secondary discharges often occur and discharges easily concentrate on the same location, which leads to ...
