Three methods for grinding: cross grinding, slanted tool axis grinding and parallel grinding, were carried out to study the machinability of tungsten carbide mold for glass formed aspheric lens. In our research, the optimum grinding conditions were investigated in terms of feed rate, relative velocity of wheel and work piece, tool marks and surface roughness. It is shown that cross grinding are most efficient in removal ratio but poor in surface roughness. In addition, tool marks of each method were differentiated on direction and shape. 더 자세한 내용은 첨부파일 참조
