Grinding forces are very important phenomena of the grinding process. They are also the necessity of the design and the selection for grinder. The higher grinding forces, the more difficult removing material from the workpiece surface. In order to obtain more knowledge about the grinding mechanism of ceramics and steels, a comparative study of ELID (ELectrolytic In-process Dressing) grinding forces of these two kinds of materials was investigated on the same experimental conditions. This experiment was carried out on a surface grinder. Four types of materials, such as ceramics of SiC and ZrO2, steels of SKD11 and STAVAX, were selected. In grinding process, grinding forces were measured by a three-component forces dynamometer. It was found that the grinding forces of SKD11 and STAVAX were greater than these of SiC and ZrO2 on the same conditions. Finally, these phenomena were explained on the basis of the cutting principle.
