Abstract

Spark assisted chemical engraving (SACE) technology has the potential for micro machining glass with advantages of simplicity, high aspect ratio and less micro cracks. Typical micro SACE process utilizes cylindrical tool and suffers from poor electrolyte circulation along with machining depth. This work employed φ200µm tungsten carbide drill to experimentally fabricate micro holes on Pyrex Glass by applying SACE process. On the rotation of the drill, the micro grooves of the drill are capable of enhancing electrolyte circulation within machining zone and thus improve the processing performance. Several effects of process factors on drilling results were evaluated correspondently. The results revealed that machining time, drill rotation direction and rate, and the contact force affected the processing performance markedly. A deep hole of 245 ¿m in entrance diameter and 8.8 in aspect ratio was obtained by optimal process parameters. Tool wear has also been discussed herein.
