Abstract

During EDM, orbital tool actuation can decouple the size of tool electrode from the size of cavity. In present study, experimental investigation is carried out to study the effect of orbital tool actuation along helical path on material removal rate and Surface roughness. The experimental results have been compared with those under conventional cavity sinking process. A circular hole having 10 mm diameter and 10 mm depth is generated on Inconel 718 using copper electrode. It is observed that orbital tool actuation improves MRR as compared cavity sinking process at machining depth of 10 mm. Further, lower surface roughness is observed with orbital EDM relative to cavity sinking process. The surface characteristics under different machining conditions are reported with the help of SEM images. Thus while machining deep holes, orbital tool actuation along helical path substantially improves MRR and surface finish relative to cavity sinking process under same machining conditions.
