| Outline of Final Research Achievements |
Monocrystalline diamond tools are finished by experts of their grinding or polishing. In this study, forming and texturing of monocrystalline diamond tools were performed by using picosecond laser. Influence of the texturing on the rake face of monocrystalline diamond tool was also examined. After conducting a series of experiments and clarifying the influence of the laser irradiation parameters on the generated single groove's dimensions, forming of tool tip was conducted. As a result, it is clarified that even the shape which is difficult to grind can be formed by using the picosecond laser with a few micro meter precision. Through an actual cutting experiment of aluminum, it is also confirmed that the texturing on the rake face of the monocrystalline diamond tool is beneficial to reduce the adhesion of the workpiece material.
