Abstract: In one embodiment, a tool used for creating grooves in a microreplication tool is described. The tool includes a mounting structure and a multi-tipped diamond mounted in the mounting structure. The different tips of the diamond may correspond to different grooves to be created in the microreplication tool. In this manner, the creation of a microreplication tool using a diamond can be simplified and/or improved.

Abstract: The present invention provides master and production tools and method for making these tools. The master tool includes a plurality of three-dimensional shapes upraised from a major surface of the master tool. Each of the 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 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 three-dimensional shaped abrasive composites.

Abstract: An abrasive article is provided having a sheet-like structure having a major surface having deployed in fixed position thereon a plurality of abrasive three-dimensional abrasive composites, each of the composites comprising abrasive particles dispersed in a binder and having a precise shape defined by a distinct and discernible boundary which includes specific dimensions, wherein the precise shapes are not all identical.

Abstract: 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.
