Design of a diamond tool for laser in situ assistance

Abstract Laser in-situ auxiliary processing is an advanced hard and brittle material processing method. In order to improve the utilization rate of the laser in the processing process and better realize the thermal softening effect on hard and brittle materials, the transmission model of the laser and diamond tools was established by COMSOL, and the laser transmission through the rake face of the ordinary arc-edged diamond tool was analyzed. A diamond tool with laser incident surface parallel to the rake surface is designed. The laser incident surface of this diamond tool is parallel to the rake surface, so that the laser can penetrate the diamond rake surface perpendicularly, which is compared with the ordinary circle. The arc turning tool can significantly improve the beam quality, increase the power density of the laser penetrating the tool, and obtain the temperature field change of the diamond tool during laser irradiation and the rule of tool tip deformation. The research is to improve the laser in-situ assisted diamond tool Machining accuracy provides theoretical basis. (paper)
