| Outline of Final Research Achievements |
The visualization system of stress distribution under ultrasonic vibration-assisted cutting condition is constructed to investigate the cutting phenomenon. The instantaneous stress distribution on workpiece was visualized by photoelastic method in combination of pulse laser emission synchronized with vibration of cutting edge. Orthogonal cutting test was carried out at low cutting speed relative to vibration speed. The photographic system divided the ultrasonic vibration period of 36.2 μs into 360 frames. It was experimentally confirmed that the stress distribution under vibration-assisted condition showed the periodical change synchronized with insert vibration. The imaging system is able to show the periodic change of stress distribution in ultrasonic frequency band. Remnants formed due to elastic deformation of the workpiece were examined. The vibration cutting dramatically reduced the elastic deformation and the vibration amplitude had effect on the amount of remnant thickness.
