Flushing of the Electrode Gap in Electrical Discharge Machining of Functional Materials

Russian Engineering Research Aims and scope

Abstract

The flushing of the electrode gap in the deep-hole electrical discharge machining (EDM) of titanium is simulated. ANSYS CFX 20.1 software is used to model the flux distribution with three values of the machining depth (2, 10, and 15 mm) and three values of the nozzle inclination (15°, 25°, and 75°). In the machining of titanium, the inclination of the flushing nozzles must be taken into account in order to increase the productivity in machining deep sockets. The productivity is greatest with 15° inclination. Laminar motion predominates. With the given nozzle inclination, the liquid pressure and debris discharge are stable when the machining depth is both 2 and 15 mm.
