| Research Abstract |
In this study, the occurrence of loading was compared between our proposed fixed-abrasive tool and general-purpose tools. It was found that the causes of loading were (1) the formation of a chip pocket due to a high abrasive-grain density, (2) an increase in the contact area between the tool and the workpiece, and (3) the absence of continuous pore around the abrasive grains. Moreover, swarf larger than the grain size were observed for the tool with loading, whereas no such swarf were observed for the tool without loading even when the tool contained fine abrasive grains. In the manufacture of fixed-abrasive tools, therefore, the abrasive grains percentage in the tools should be50% or lower, regardless of their grain size.
