Abstract: Optomechanical tools are disclosed. The optomechanical tools include a body of material having an entrance face, a rake face, a flank face, a rake side face, and a flank side face. The rake side face and the flank side face are connected to the entrance face. The rake side face is connected to the rake face. The flank side face is connected to the flank face. The rake face is connected to the flank face to define a curved cutting edge. The entrance face extends away from the flank side face to define a back-relief angle. The rake face extends away from the rake side face to define a rake angle. The entrance face is configured to direct a light beam toward one or more of the rake face, the flank face, the rake side face, the flank side face, and the curved cutting edge and through one or more of the rake face, the flank face, and the curved cutting edge, causing the light beam to refract onto the workpiece. Systems are also disclosed.

Abstract: A laser-transmitting machining tool is disclosed. The laser-transmitting machining tool has a plurality of faces including an entrance face, a rake face, a flank face connected to the rake face, a rake side face extending between the entrance face and the rake face, and a flank side face extending between the entrance face and the flank face. The connection of the rake face to the flank face defines a cutting edge. The rake face extends away from the rake side face to define a rake angle. The entrance face is configured to receive and refract a laser beam to the rake face, the flank face, and the cutting edge for causing the laser beam to refract into and heat the workpiece at a compression region extending proximate at least the rake face and a tensile region extending proximate the flank face. A system for machining a workpiece is disclosed. A method for machining a workpiece is also disclosed.
