Problems solved by technology

Compared with one-dimensional ultrasonic vibration cutting, two-dimensional composite ultrasonic vibration cutting can further improve the machining accuracy of the workpiece, reduce the surface roughness of the workpiece, effectively reduce the cutting force, increase the material removal rate, prolong the tool life and significantly improve the processing efficiency etc., but two-dimensional composite ultrasonic vibration cutting requires at least two ultrasonic vibration sources, which has the disadvantages of complex structure, difficult control and high cost.
