Abstract
A new dressing method is introduced, in which. a single point diamond dresser is mounted on eccentrical rotating spindle and fed parallel to the wheel surface, for higher performance of grinding wheel. It is expected in this method that cutting edges on the wheel surface are sharpened by more chance of cleavage fracture, because grains are forced in various directions. Sharpness coefficient of cutting edge, estimated initial wear area and mean number of cutting edges are defined ascharacteristic values to quantify the condition of cutting edges on the wheel surface. The dressing process is significantly affected by the revolution ratio of dresser to wheel and the decimal place of the ratio should be selected except 0 and 0.5. Cutting edges generated in the new method are sharper, while the number of cutting edges is slightly fewer than in conventional one. Grinding force and residual stock are smaller while surface roughness and wheel wear are larger in this method and grinding ability is maintained longer as compared with conventional one.
