Abstract:
1. A method for manufacturing abrasive tools having individual abrasive grains placed in a controlled, random spatial array such that the individual grains are non-contiguous, comprising the steps of: (a) selecting a two-dimensional planar area having a defined size and shape; (b) selecting a desired abrasive grain grit size and concentration for the planar area; (c) selecting a series of coordinate value pairs (x (d) decoupling each selected coordinate value pair (x (e) randomly selecting from the sets of x and y values a series of random coordinate value pairs (x, y), each pair having coordinate values differing from coordinate values of any neighboring coordinate value pair by a minimum value (k); (f) generating an array of the randomly selected coordinate value pairs having sufficient pairs, plotted as points on a graph, to yield the desired abrasive grain concentration for the selected two dimensional planar area and the selected abrasive grain grit size; and (g) centering an abrasive grain at each point on the array.
