Abstract
Abrasive sheet materials, abrasive sheet materials with island distributions of abrasive particles, processes for manufacture of abrasive sheet materials with minimized abrasive content (with monolayers and as few as four layers of abrasive particles), processes for using the abrasive sheeting in high speed lapping/abrading processes, and apparatus for using the abrasive sheeting are described. The process for manufacturing the abrasive sheeting provides an economical method for providing improved quality sheeting, while also allowing for greater control over the shape and distribution of abrasive islands on the sheet than is available from present processes of manufacture.
