Disclosed is a cost effective and reliable method to enable mass production of the unique features of the fiber rich, working contact surface of commutation brushes. A key element to this process involves beam shaping and raster scanning of a high spectral frequency laser to perform a critical cut and sculpture operation. This disclosure describes the critical details of a laser process that is unique to this application.
