Abstract
An abrasive article having an array of abrasive members with an elastomeric support that permits each abrasive member to move independently in at least pitch and roll. Each abrasive member maintains a fluid bearing (air is the typical fluid) with the substrate. The abrasive members are capable of selectively engaging with nanometer-scale and/or micrometer-scale height variations and micrometer-scale and/or millimeter-scale wavelengths of waviness, on the surfaces of substrates. The spacing and pitch of the abrasive members can be adjusted to follow the topography of the substrate to remove a generally uniform layer of material; to engage with the peaks on the substrate to remove target wavelengths of waviness; and/or to remove debris and contamination from the surface of the substrate.
