Abstract (en)
[origin: WO2019207423A1] The present disclosure provides an abrasive article (10). The abrasive article (10) has a direction of use, a y-axis and a z-axis orthogonal to the y-axis and the direction of use. The abrasive article (10) further includes a backing (12) and shaped abrasive particles attached to the backing. About 5% to about 100% of the shaped abrasive particles (14) independently include a first side surface (16), a second side surface (18) opposed to the first side surface (16), a leading surface (20) connected to the first side surface (16) at a first edge (24) and connected to the second side surface (18) at a second edge (26), a rake angle (30) between the backing (12) and the leading surface (20) in a range of from about 10 degrees to about 110 degrees, and a z-direction rotational angle (50) between a line (52) intersecting the first edge (16) and second edge (18) and the direction of use (22) of the abrasive article (10) in a range of from about 10 degrees to about 170 degrees.
