Investigation of Surface Integrity in Conventional Grinding of Ti-6Al-4V


Article Preview

This paper investigates the surface integrity of Ti-6Al-4V in conventional grinding using SiC abrasive, it includes surface roughness, surface topography, surface residual stress and metallurgical structure alteration. The experiment result indicated that grinding depth and feed rate have significant effect on surface roughness. Workpiece ground surface was free of crack, but severe plastic deformation layer and light burn appeared because of chemical reactions and mechanical factors. Ground surface was in a state of high tensile residual stress, thermal cycling of surface layer had the greatest effect. The machined surface experienced microstructure alteration on the top layer of ground surface, a heat-affected zone (HAZ) was observed.
