An investigation of attritious and fracture wear of grinding wheels in precision grinding is described in a two paper sequence. Attritious wear, the subject of this first paper, refers to the dulling of the abrasive grain due to rubbing against the workpiece surface. The amount of dulling, measured by the area of the wear flats on the surface of the wheel, is found to be directly related to the grinding forces. In general, both the vertical and horizontal grinding force components increase linearly with the wear flat area. This is explained by considering the grinding force as the sum of a cutting force due to chip formation and a sliding force due to rubbing between the wear flats and workpiece. Related studies of wheel dressing, surface finish, and workpiece burn are also presented.
An investigation of the thermal aspects of grinding is described in a two paper sequence. This first paper is concerned with the distribution of the total grinding energy among chip formation, plowing, and sliding energy components, and the portions of each of these energies which are conducted as heat to the workpiece. The results indicate that virtually all the sliding and plowing energies, and approximately 55 percent of the chip formation energy, are conducted as heat to the workpiece. In the second paper, these results are related to grinding temperatures and workpiece burn.
