摘要： A method and apparatus for knurling a workpiece in which the knurl pattern includes grooves of at least two different configurations. The apparatus includes a knurl wheel holder that allows angular rotation of the knurl wheel about the holder longitudinal axis while maintaining the knurl wheel point of contact on the longitudinal axis. The apparatus also includes a knurling wheel that includes teeth of at least two different configurations. Also disclosed is a method of molding a molded article with the knurled workpiece to impart the inverse of the knurl pattern onto the molded article, such a molded article, a method of forming a structured abrasive article with the molded article, and such an abrasive article.

摘要： 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.
