Abstract In order to exploring an effective way of improving the ground surface quality of ferrite ceramics,the influence of grinding depth and workpiece speed on the ground surface roughness and its material removal mechanisms were studied through the grinding experiment with resin bonded diamond wheel.Meanwhile single factor test and variance analysis method were adopted to analyze the R_a data,and then the grinding surface topography was analyzed.The results showed that the surface roughness and brittle.fracture marks increased with the increase of grinding depth and workpiece speed,while ductile machining marks decreased.The grinding depth had more effect on R_a than working speed.Consequently,in order to improve the grinding efficiency,small grinding depth(5 µm)and high workpiece speed(10 m/s)are proposed.On the other hand,optimized grinding depth(5 µm)and low workpiece speed(5 m/s)are necessarily suggested for finishing process to reduce surface roughness and improve the surface ductility.
