Outline of Final Research Achievements

We propose a novel, on-machine method of measuring a cutting tool edge by using the cutting fluid on the tool surface. Because of an environment of on-machine tool profile measurement, it is difficult to measure a cutting edge profile with conventional optical methods. To overcome this problem, we propose a profile measurement method that uses confocal fluorescent detection from the cutting fluid on the tool surface. Moreover, for precise measurements, a method that corrects for the thickness of the cutting fluid is provided. The proposed method was fundamentally validated by measurement results for detailed tool wear profiles. This novel measurement technique produces results with sub-micron accuracy.
