In recent years, the Electrochemical Discharge Machining (ECDM) process emerged as
superseding machining process owing to its capability to processing of conductive and non-
conductive materials. The micro-machining of Carbon Fibre Reinforced Polymer (CFRP)
composite is successfully attempted in this work by drilling of micro-holes. The experiments
were planned using L 9 orthogonal array Taguchi's methodology with applied voltage,
electrolyte concentration and inter-electrode gap as process parameters. The Material …

Carbon fibre reinforced polymer (CFRP) composite is highly acceptable in aerospace,
automotive and structural applications. However, the machining of CFRP composite by
traditional processes is challenging task owing to its semi-conductive and fibrous nature. In
the recent years, the electrochemical discharge machining (ECDM) process has been
recognized as novel method for micro-machining of conductive and non-conductive
materials. In this study, an attempt has been made to micro-drilling of holes on carbon fibre …
