Abstract
A kind of elastic coated abrasives used for polishing large mould surface, such as automobile panel mould, is investigated in this research. Many polishing experiments were finished by using elastic coated abrasives in order to study the effects of grit and workpiece material on surface roughness and machining efficiency. It is concluded that surface roughness is minimum and polishing efficiency is the highest when using 120# abrasives at the same condition, surface roughness is the lowest and polishing efficiency is the highest for AISI 1045 steel in three materials. The difficulty of material removal is different if the textures prior to polishing are different in workpiece surface. Surface texture prior to polishing has effects on surface roughness and polishing efficiency. The research results provide foundation for process planning to achieve good surface roughness and high efficiency in the future research.
