The overall performance of the grinding wheel is difficult to analyze, as it is a compilation of individual abrasive grit contributions. The single grit scratch test is useful to investigate the effect of the individual grit effect on the work material. A vacuum-brazed diamond dresser is developed for the single grit scratch experiment. Partially stabilized zirconia is used as work material to study the mechanics of material removal and mode of grit failure. The experiments were performed in dry conditions by varying the wheel speed, table feed, and depth of cut. The grit failure mechanism has been analyzed using a scanning electron microscope image and correlated with the induced force during the scratch test. The results show that the diamond microcracking was observed after 370 mm of grinding scratch marks. And the maximum tangential and normal force withstand by the diamond grit is 13.09 N and 19.65N, respectively.

Abstract


The overall performance of the grinding wheel is difficult to analyze, as it is a compilation of individual abrasive grit contributions. The single grit scratch test is useful to investigate the effect of the individual grit effect on the work material. A vacuum-brazed diamond dresser is developed for the single grit scratch experiment. Partially stabilized zirconia is used as work material to study the mechanics of material removal and mode of grit failure. The experiments were performed in dry conditions by varying the wheel speed, table feed, and depth of cut. The grit failure mechanism has been analyzed using a scanning electron microscope image and correlated with the induced force during the scratch test. The results show that the diamond microcracking was observed after 370 mm of grinding scratch marks. And the maximum tangential and normal force withstand by the diamond grit is 13.09 N and 19.65N, respectively.
