Abstract
In the high-efficiency grinding process using a CBN wheel, it is necessary to minimize the amount of wheel removed by truing (hereinafter referred to as truing amount) to reduce tool costs. In this study, the relation of surface roughness and grinding resistance was investigated when the tip of the abrasive grain's cutting edge was removed in submicron order (hereinafter referred to as submicron removal) to reduce the truing amount. The results confirmed that the surface roughness is small while suppressing the increase in grinding force by reducing flattening of the tip of the cutting edge and the increase in number of cutting edges by submicron removal compared to conventional truing.
