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.
