Enhancement the performance of wire cutting process by additives nanopowder alumina (Al2O3)

Wire Electrical Discharge Machining (WEDM) is a non-traditional thermal machining process used to manufacture irregularly profiled parts. WEDM includes high rates of cutting and superior quality in improving machining performance onto hard materials. Today the electric wire machine plays an im...
