Abstract:
Abrasive articles, and methods of making abrasive articles by using a laser to convert (e.g., cut) at least a portion of the abrasive coating to form the abrasive article. The method includes laser propagation impinging on the abrasive back side (opposite the abrasive coating) and progressing through to the abrasive side. Such a process inhibits ridging effects around cut regions (e.g., openings) on the front side.
