Fluid Dynamics in Electrode Flushing Channel and Electrode-Workpiece Gap During EDM Drilling
2018
Procedia CIRP
Evacuation of removed material is a key limitation factor in EDM drilling, as debris particles remaining in the gap between electrode and workpiece could reattach to the workpiece or cause ineffective discharges. In order to increase particle evacuation rate, electrodes with internal flushing channels are used. In this work, the influence of drilling conditions to the pressure drop and dielectric flow during EDM drilling is investigated analytically and through computational fluid dynamics
