The invention discloses an exciting vibration-aided milling method, which comprises the following steps: a workpiece to be processed is fixed on a vertical vibration plate, a milling cutter is adjusted to a processing position, then a four-channel signal-generator is turned on , an electric signal generated by the four-channel signal-generator is transmitted to a four-channel power amplifier, after the electric signal is amplified by the four-channel power amplifier, and then is output in a vibrating table, the electric signal is received by the vibrating table, transverse single-direction vibration, vertical single-direction vibration, and transverse and vertical bidirectional vibration are realized by a vertical piezoelectric ceramic oscillator and a transverse piezoelectric ceramic oscillator which are arranged in the vibrating table, the workpiece to be processed is driven for one-dimensional or two-dimensional mechanical oscillation, and exciting vibration-aided milling can be carried out on the workpiece. According to the invention, vibration direction precision during the processing step can be greatly increased, stability and processing precision during the vibration processing step can be effectively guaranteed, unidirectional or bidirectional vibration processing can be realized, processing application scope is developed, and processing efficiency is increased.
