A study on Wire Breakage in Electrical Discharge Machining of Polyurethane Foam

The present work discusses the feasibility of cutting polyurethane foam using wire electrical discharge machining (WEDM) process. The foam consists of nickel copper coated polyester (PET) fabric. Three different thicknesses of foam constitute to different surface and volume resistivity were chosen a...
