| Outline of Final Research Achievements |
In this research, an ultra-precision form measurement has been verified for three dimensional measurement of micro-cutting edge of the diamond cutting tools. A reversal edge of the cutting edge, which is made by the indentation of the diamond cutting edge on the soft material, is created for the canceling of the measurement errors due to the AFM probe scanning. A force-sensor integrated fast tool servo (FS-FTS) was constructed for single point diamond micro-cutting and in-process measurement of both of the cutting force and tool displacement. By using the FS-FTS, the micrometric reversal edge of the cutting tool can be created during the measurement of the cutting force. Molecular dynamics (MD) simulations were introduced for the investigation and optimization of the creation of the reversal edge on the soft materials. The results of MD simulation indicated that 3D surface form of the diamond micro cutting edge could be obtained with sub-nanometric accuracy by using the reversal edge.
