| Abstract: | The effects of the diamond tool on the ductile to brittle transition of the glass in ordinary cutting, conventional vibration cutting and ultrasonic elliptical vibration cutting are investigated experimentally. It is understood that the critical depth of cut for the ductile cutting of the brittle material in two kinds of ultrasonic vibration cutting can be increased as compared to ordinary cutting. The theoretical formulae for the critical depth of cut in ultrasonic elliptical vibration cutting and conventional vibration cutting are derived theoretically. The reasons for the increase of the critical depth of cut in ultrasonic elliptical vibration cutting and conventional vibration cutting are analyzed. |
