    Abstract: Structured abrasive articles include a backing and shaped abrasive composites secured to the backing. The shaped abrasive composites include abrasive grits dispersed in a binder matrix. The shaped abrasive composites include a bottom surface and a top surface opposite and not contacting the bottom surface, and at least three sidewalls abutting both the bottom and top surfaces and two other sidewalls. In one embodiment, at least two cusps are formed by the top surface and individual sidewalls. In another embodiment, the top surface includes at least two triangular facets that contact at least two respective sidewalls and at least two cusps. The top surface includes at least one interior recessed portion nearer the cusps than the bottom surface. Methods of abrading a workpiece using the structured abrasive article are also disclosed.

    Abstract: A structured abrasive article comprises a backing, and an abrasive layer disposed on and secured to the backing. The abrasive layer comprises shaped abrasive composites, each comprising abrasive particles dispersed in a binder. Each the shaped abrasive composites independently comprises: a base disposed on the backing; a plurality of walls extending away from the base, and a grinding surface not contacting the base. Adjacent walls share a common edge. Each wall independently forms a dihedral angle with the base of less than or equal to 90 degrees. The grinding surface has a plurality of: cusps, and facets that contact a recessed feature. At least a portion of the recessed feature is disposed closer to the base than each of the cusps. Each cusp is formed by an intersection of two of the walls and at least one of the facets. Use of the structured abrasive article to abrade a workpiece is also disclosed.

    Abstract: Precursor alpha alumina abrasive particles in a mold are subjected to a drying process that cracks or fractures at least a majority of the precursor abrasive particles into at least two pieces thereby producing abrasive shards having a smaller size than the mold cavity from which they were made. The smaller abrasive shards, once formed, could be reassembled like jigsaw puzzle pieces to reproduce the original cavity shape of the mold from which they were made. The cracking or fracturing of the precursor abrasive particles is believed to occur by ensuring that the surface tension of the abrasive dispersion to the walls of the mold is greater than the internal attractive forces of the abrasive dispersion as the abrasive dispersion is dried within the mold cavity.

    Abstract: An abrasive comprising shaped abrasive particles each with an opening. The shaped abrasive particles are formed from alpha alumina and have a first face and a second face separated by a thickness t. The opening in each of the shaped abrasive particles can improve grinding performance by reducing the size of a resulting wear flat, can provide a reservoir for grinding aid, and can improve adhesion to a backing in a coated abrasive article.

    Abstract: By controlling the process parameters and by using a polymeric production tooling having a plurality of mold cavities, different types of shaped abrasive particles selected from the group consisting of abrasive shards, dish-shaped abrasive particles, and shaped abrasive particles with an opening can be produced from the exact same mold. In one embodiment, the mold comprised a plurality of equilateral triangles and fractured precursor abrasive particles, dish-shaped precursor abrasive particles, or precursor shaped abrasive particles with an opening were produced from the same mold.

    Abstract: An abrasive article includes an array of protruding abrasive units. Each unit has a base and a distal apex that is off-center from the base when projected on to a plane that is coplanar with the base. The abrasive article includes a backing bonded to an abrasive coating formed to include the aforementioned abrasive units. Methods for making the abrasive article include nipping a production tool, an abrasive slurry, and the backing. A binder within the slurry is cured during fabrication. The abrasive article may be used to abrade a workpiece.
