| Outline of Final Research Achievements |
For the quantitative evaluation of edge forms of next-generation high-precision cutting tools, a measurement method, in which a focused laser beam referred to as the micro-laser probe is employed to realize non-contact and high-speed tool edge evaluations, has been developed. A prototype optical setup with a high-precision objective lens for the micro-laser probe has been developed, and its basic characteristics have been evaluated in experiments. The experimental results have demonstrated that the developed micro-laser probe has a high measurement resolution beyond the diffraction limit for tool edge measurement. It has also been verified that the developed micro-laser probe can be applied for the quantitative evaluation of a tool edge contour. Furthermore, a feasibility of the micro-laser probe for evaluation of a tool cutting edge radius has also been verified throughout theoretical and experimental investigations.
