58th CIRP General Assembly
Manchester, August 25, 2008

19. Conclusions & Outlook
Proof-of-concept of an innovative abrasion-assisted wire EDM process has been presented
The process has the potential to significantly enhance the removal rate and the quality of the machined surface, particularly for metal matrix composites that are difficult to wire EDM
The process is perhaps best implemented on a twin-wire machine tool
Research effort is required to formulate wires with aluminum oxide abrasives, with a core that has good sparking and grain retention characteristics
Electrical discharges could possibly enhance wire sawing of brittle materials through controlled thermal shock-induced fracture
