    Abstract: The present disclosure provides abrasive articles that include an abrasive layer having a contact surface, a first layer coupled to the abrasive layer, and a second layer coupled to the first layer. The first layer is configured to provide contact pressure to the abrasive layer, such as through a higher hardness than the second layer. The second layer is configured to provide conformability to the abrasive layer, such as through a higher compressibility than the first layer. The resulting abrasive articles may exert a consistent contact pressure against a substrate with increased conformability around the substrate, reduced hysteresis, improved removal rate consistency, and/or improved lifetime over abrasive articles that do not use the multiple layer construction described above.

    Abstract: A method of tuning the contact pressure across an abrasive disc is presented. The method includes coupling the abrasive disc to a backup pad comprising a pressure tuning feature that causes an experienced pressure by a worksurface, across a radius of the abrasive disc, to be uniform. The method also includes abrading a worksurface by contacting the abrasive disc to the worksurface. The backup pad causes the abrasive disc to have a cut rate that is substantially uniform across the surface of the abrasive disc when compared to the abrasive disc on a backup pad with no pressure tuning feature.

    Abstract: According to one embodiment, a method can comprise: providing a tool that has a first portion that comprises a first material and a second portion that comprises a second material, wherein the second material differs from the first material and the tool is subject to a magnetic field, and wherein the first material and the second material are provided such that the magnetic field is relatively stronger at and adjacent the first portion relative to the magnetic field at and adjacent the second portion; positioning a surface adjacent to the tool so as to be subject to the magnetic field; and disposing magnetizable abrasive particles on the surface, wherein the magnetizable abrasive particles are attracted to an area on the surface adjacent the first portion where the magnetic field is relatively stronger so as to provide for at least one of a desired orientation, placement and alignment of a majority of the magnetizable abrasive particles on the surface.
