Abstract

See full text

A variable-frequency ultrasonic machining system for a computer numerical control milling machine including a cutting force detection unit, a temperature sensing unit and a processor. The processor receives sensing signals of the cutting force detection unit and the temperature sensing unit, processes the received sensing signals according to a set program, and sends control signals to an ultrasonic drive power supply and a corresponding servo motor, respectively. By adjusting the ultrasonic vibration frequency or the frequency of the frequency converter of the CNC milling machine in the machining process, the system ensures the continuity of ultrasonic-assisted milling of a part with a complex curved surface in case of uneven cutting allowance, and improves efficiency of ultrasonic machining.
