Abrasive article manufacturing processes and workpiece refining with the same production tool for manufacturing the same and master die production process for forming the same

摘要

The present invention provides a master tool and method for making a master tool. The master tool includes a plurality of precise three-dimensional shapes upraised from the surface of the master tool. Each of the precise shapes is defined by a distinct and discernible boundary including specific dimensions, wherein not all said three-dimensional shapes are identical. The master tool of the present invention can be used to form a production tool containing a plurality of precise three-dimensional-shaped cavities. The production tool can be used in the manufacture of abrasive articles to shape an abrasive slurry into an array of precise three dimensional-shaped abrasive composites.
