Abstract

The characteristics in wear of grinding wheels are investigated over an ordinary range of grinding conditions. Further, the size distribution of abrasive grains worn from a grinding wheel is measured. Experimental results reveal the rapid increase of wear as the grinding condition is brought severe. The size distribution, however, does not change remarkably throughout the experiments.<BR>The effect of the grinding condition on wear is discussed in terms of the life of an active grain. The discussion leads to the conclusion that the life of a grain involves only a parameter, that is, the grain depth of cut which varies with the work speed and the vertical feed.
