Bonded abrasive article

A bonded abrasive article comprising:

• a plurality of shaped abrasive particles, said shaped abrasive particles each comprising a first side and a second side separated by a thickness t, wherein said first side comprises a first face having a perimeter of a first geometric shape, wherein said thickness t is equal to or smaller than the length of the shortest side-related dimension of the particle;
• a bonding medium comprising a vitreous bond;
• a surface profile and a grinding surface, wherein the grinding surface is configured to contact a workpiece and impart a negative image of the surface profile onto the workpiece;
• and
• wherein the surface profile comprises an edge with a plurality of indentations, wherein each of the shaped abrasive particles has a largest dimension of about the same order of magnitude as one of the plurality of indentations, wherein the surface feature repeats along the surface profile such that a pattern of ridges and valleys are ground into the workpiece.

A bonded abrasive article, the article comprising:

• an active surface configured to engage a workpiece, wherein the active surface comprises a surface profile and an article thickness, wherein the bonded abrasive article is configured to engage the workpiece along the article thickness such that a negative image of the surface profile is imparted to the workpiece through an abrading operation, wherein the surface profile comprises a repeating pattern;
• a plurality of shaped abrasive particles bonded within a binding medium, wherein each of the shaped abrasive particles comprising a first dimension, a second dimension, and a thickness, wherein the thickness is less than the first dimension;
• and
• wherein the repeating pattern comprises a sawtooth, and wherein the repeating pattern is configured to impact a threaded surface on a workpiece;
• and
• wherein the first dimension is about the same order of magnitude as the feature dimension.
