First Claim
1. A laser-transmitting machining tool for machining a workpiece, the laser-transmitting machining tool comprising:
- a body of material having 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,wherein the connection of the rake face to the flank face defines a cutting edge,wherein the entrance face is configured to receive and refract a laser beam to the rake face, the flank face, and the cutting edge, 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, andwherein the rake face extends away from the rake side face to define a rake angle and the flank face extends away from the flank side face to define a flank angle relative to the rake angle, the rake angle is sized to define one of the following rake angles including;
a highly negative rake angle causing the compression region of the workpiece to be a highest compression region and the tensile region of the workpiece to be a lowest tensile region;
a midrange negative rake angle causing the compression region of the workpiece to be a high compression region and the tensile region of the workpiece to be a low tensile region;
a low-range negative rake angle causing the compression region of the workpiece to be a medium compression region and the tensile region of the workpiece to be a medium tensile region;
a zero rake angle causing the compression region of the workpiece to be a low compression region and the tensile region of the workpiece to be a high tensile region; and
a positive rake angle causing the compression region of the workpiece to be a lowest compression region and the tensile region of the workpiece to be a highest tensile region.

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.
