Common Machining Strategies

Abstract

Spark-assisted chemical engraving (SACE) can be used to machine holes, 2D and 3D structures. Today, SACE is mostly used for glass microdrilling, which was the first application developed for this technology. Much less developed SACE machining strategies are wire electrochemical machining and the recently introduced lathe-type machining. SACE is also applied to materials other than glass, but compared with glass micromachining, knowledge is still very scanty.
