Abstract
The final objective of this investigation is an invention of theory and technics for multiple precision cylindrical machining with combining ultrasonic vibration cutting on thrust force direction, and superposition superfinishing process. This finishing process is a high efficient mirror machining providing (20-50Hz) low frequent vibration and ultrasonic vibration above 20 kHz to fine abrasive stone. In this report, ultrasonic vibration cutting mechanism on thrust force direction is analyzed and it is shown that high precision machining can be achieved by using the effect of insensitive vibration cutting mechanism. And cutting phenomenon are observed by some experiments. In the results, it is confirmed that chips on low feed rate and high cutting speed conditions have been cut to pieces as same as analyzing, and that work displacement on vibration turning can be reduced according to growing up tool amplitude. This report indicates that ultrasonic vibration cutting on thrust force direction can be possibly used for multiple precision cylindrical machining.
