Abstract
This paper was dedicated to elucidate an investigation of grinding force and workpiece surface of Titanium alloy TA15 in dry grinding by using zirconia alumina belts. The grinding forces were measured by KISTLER 9265B dynamometer. Machined surface morphology and the metallographic structure were observed using 3D viewer microscope. Surface roughness was measured using Mahr Perthometer M1 instrument. The surface microhardness for ground surface was detected by HVS-1000 instrument. The good results were obtained, as follows: low surface roughness, high surface hardness, no microstructural damage, in the form cracks or recrystallisation of the grinding surface, the stable grinding performance with zirconia alumina belts, the small plastic deformation depth of workpiece surface (≤5μm). Therefore belt grinding showed excellent performance during grinding titanium alloy.
