Abstract
Surface integrity has a significant influence on mechanical and tribological behaviour of a material in high heat resisting applications. Non-traditional machining methods like electrical discharge machining (EDM), laser beam machining (LBM), electrochemical machining (ECM), ultrasonic machining (USM) etc. are commonly used to processes the hard materials. Wire EDM (WEDM) is most efficient spark erosion process to shape the hard materials into desired geometry and to modify their surface characteristics. In present book chapter, the experimental results pertaining to surface modification of difficult to machine materials namely WC-Co and Nimonic-90 are presented. Surface was modified through rough cut, trim cut and combination of rough and trim cuts in wire electrical discharge machining (WEDM). Surface integrity was measured in terms of surface roughness (SR), crack size and recast layer thickness. In all the cases, surface integrity was dissimilar for both the difficult to machine materials. Scanning electron microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) analysis was used to evaluate the surface morphology of WEDMed surfaces.
