During machining, ultrasonic vibration of workpiece can improve the machining process.
In the process of processing, the workpiece processing technology is improved by ultrasonic vibration.
Based on analyzing the kinematics mechanism of ultrasonic vibration drilling, the calculating formulas of critical drilling velocity are deduced, and the mechanics of improving the aperture quality by the ultrasonic vibration drilling is analyzed.
Experiments of diamond turning of stainless steel are taken on a fine lathe by utilizing ultrasonic vibration.
Based on the cutting experiment, the process and effect of ultrasonic vibration boring for precise deep holes by using the double-edge boring cutter are researched.
The life of the drill bit, the burr at the outlet and the roughness of the machined surface when drilling micro holes with ultrasonic vibration are studied.
Finally, it presents an applied fuzzy control algorithm, which can be used as a dynamic impedance matching approach for the power ultrasonic vibration system.
The author apply ultrasonic vibration to the turning of thin-wall pieces to reduce the deformation, and an tools-tip height adjustment mechanism adapted to the vibration cutting system was developed.
Thus, the relationship between the rotating speed of the motor and some factors, such as the ultrasonic vibration of the stator, the fluid acoustic streaming field and the rotor radius, etc.
