    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 translation: 结构化研磨制品包括固定到背衬的背衬和成形的磨料复合材料。 成型的磨料复合材料包括分散在粘结剂基质中的磨粒。 成形研磨复合材料包括底表面和与底表面相对且不接触的顶表面，以及至少三个侧壁邻接底表面和顶表面以及两个其它侧壁。 在一个实施例中，由顶表面和单个侧壁形成至少两个尖。 在另一个实施例中，顶表面包括至少两个接触至少两个相应侧壁和至少两个尖端的三角形小平面。 顶表面包括比底表面更靠近尖端的至少一个内凹部。 还公开了使用结构化磨料制品研磨工件的方法。
