Shaped abrasive particles with sharp edges, methods of manufacture, and articles including same

A method of making shaped abrasive particles is disclosed. The method includes filling a cavity of a tool with an abrasive particle precursor material. The cavity has at least an inner surface extending downwardly from the tool top surface at an angle. The method further includes leveling the abrasive particle precursor material such that a top surface of the abrasive particle precursor material is flush with the tool surface such that a sharp portion is formed along an intersection between an inclined wall of the tool cavity and the tool surface, and the sharp portion is in the same plane as the tool surface. The method further includes removing a dried abrasive particle precursor from the cavity of the tool. The abrasive particles have a sharp portion formed along the intersection between the inner surface and the tool surface. 公开了一种制造成形磨料颗粒的方法。所述方法包括用磨料颗粒前体材料填充工具的空腔。所述空腔至少具有以一定角度从工具顶表面向下延伸的内表面。所述方法还包括调平所述磨料颗粒前体材料，使得所述磨料颗粒前体材料的顶表面与所述工具表面齐平，使得沿所述工具空腔的倾斜壁与所述工具表面之间的交叉点形成尖锐部分，并且所述尖锐部分与所述工具表面处于同一平面内。所述方法还包括从所述工具
