Abstract
A method for forming the cutting edge and adjacent contoured surface area of rotary cutting tools utilizing a laser to remove material from the cutting end of the tool to create a predetermined point-by-point geometry is disclosed. Relatively complex surface and edge geometries may be formed by directing a laser beam toward the cutting end of the tool at an angle having a component that is normal to the surface of the cutting end. The laser beam is directed in multiple passes across the surface of the cutting end to remove material and form the desired cutting edge and adjacent three-dimensional contoured surface geometry.
