Abstract

S park A ssisted C hemical E ngraving ( SACE ) is anon conventional technology used for micro machining and drilling in non-conductive materials like glass, quartz and ceramics. The drilling can be done by penetrating the tool in work-piece. The penetrating strategies could be gravity feed drilling, constant velocity drilling and feedback based drilling. To optimize the material removal rate, without damaging the drill-hole quality, all of these strategies are investigated for practical applications, out of which gravity feed is found well characterized by now. Investigation and characterization of constant velocity drilling , still remains one of the underdeveloped areas in SACE . It is certainly presumed that investigation on forces acting at the tool-work piece contact point can be a potential tool in characterizing a constant velocity drilling process for SACE . It is also understood that studying such forces exerted on the tool during constant velocity drilling , can help in identifying and implementing the finest feedback control strategies for SACE drilling technology. This thesis report presents the outcome on investigated real-time forces, acting at the tool-work piece contact point during various constant velocity drilling experiments for SACE Technology.
