Abstract
A method of forming an abrasive article includes directing a beam of electromagnetic radiation at a starting location on an abrasive preform comprising a bonding layer and abrasive grains within the bonding layer, and increasing the power of the beam of electromagnetic radiation to a scanning power while directed at the starting location. The method further includes changing the position of the beam relative to the abrasive preform from the starting location to a second location on the abrasive preform.

A method of forming an abrasive article comprising:
- directing a beam of electromagnetic radiation at a starting location on an abrasive preform comprising a bonding layer and abrasive grains within the bonding layer;
- increasing the power of the beam of electromagnetic radiation to a scanning power while directed at the starting location;
- and
- changing a position of the beam relative to the abrasive preform from the starting location to a second location on the abrasive preform.
A method for conducting a brazing process comprising:
- providing a substrate having an abrasive region comprising a bonding layer and abrasive grains contained within the bonding layer;
- and
- changing a position of a beam of electromagnetic radiation relative to the abrasive region from a first location to a second location at a brazing rate to form a brazed abrasive region on the substrate, wherein the maximum brazing area rate Vrmax (mm2/s) is dependent upon the heat flux rate (qr) of the beam of electromagnetic radiation and the absorptivity (α) of the bonding layer material relative to a wavelength of the electromagnetic radiation.
