Experimental Study of Feed Rate, Surface Roughness, MRR and Stresses on Wire Electrical Discharge Machining

Abstract

Service qualities like wear and tear and other tribological properties of surfaces of machined components and sub-surfaces are influence by the residual stresses as it is predicted and controlled for enhanced performance. Here analytical approach, using XRD (X Ray diffraction) technique are suggested to estimate the residual stress profile through mechanical micro machining by considering variable feed rates. Lattice strain and crystallite sizes are also determined for different specimens. Correlation between feed rates and residual stresses are found significantly affecting in micro milled Low Carbon Steel Specimens.
