Abstract

The present works concerns a side flushing device for the improvement of the conventional Electric-Discharge Machining(EDM) process. In the EDM process, chips are usually generated as the workpiece is removed, and deposited between the electrode and the workpiece. This sediment degrades the surface finish of the machined product as well as the processing efficiency. In the present study, a flushing device with additional side injection equipments is proposed in order to remove the deposited chips effectively. Through numerical simulations, the validity of the proposed device is verified, and the influence of process parameters is investigated. Experiments have been also carried out in the die sinking EDM process. It was observed that the process efficiency and the surface finish are improved by virtue of the proposed flushing device.
