Abstract (en)

[origin: WO2020128845A1] The present disclosure provides systems, devices, and methods for abrasive articles and manufacturing the same. A shaped abrasive particle placement tool can include a substrate including an abrasive particle receiving surface defining an x-y plane including an x-axis and a y-axis and a back surface opposite the abrasive particle receiving surface, cavities formed in the substrate, the cavities including one or more sidewalls, the cavities including a width and length at the abrasive article receiving surface, and a depth defined by a distance the first cavities extend from the abrasive article receiving surface towards the back surface in a direction parallel to a z-axis perpendicular to the x-y plane, and respective protrusions between two or more proximate cavities, the respective protrusions extending from the abrasive article receiving surface in a direction parallel to the z-axis and away from the back surface, and shaped abrasive particles situated in the cavities.
