Technical Examples

The invention provides an abrasive article, and methods for the use and the manufacture of the article. The abrasive article comprises an abrasive surface; and a performance index associated with the abrasive article, the index indicating an aspect of the abrasive performance of the article. In abrasive applications, the performance index is used to determine initial process conditions under which the abrasive article will abrade a workpiece. A process for making the abrasive article comprises (a) providing an abrasive article having an abrasive surface; (b) providing a workpiece having an abradable surface thereon; (c) abrading the abradable surface by applying the abrasive surface against the abradable surface at a known applied pressure and velocity and relatively moving the abrasive article and the abradable surface during a predetermined period of time; (d) devising a performance index based on the abrasive performance of the abrasive article during the abrading step (c); and (e) associating the performance index with the abrasive article.
