Image Number 3 for United States Patent #7993419.
Abrasive tools contain abrasive grains oriented in an array according to a non-uniform pattern having an exclusionary zone around each abrasive grain, and the exclusionary zone has a minimum dimension that exceeds the maximum diameter of the desired grit size range for the abrasive grain. Methods for designing such a self-avoiding array of abrasive grain and for transferring such an array to an abrasive tool body are described.
