Abstract In order to study the stability of the unseparated ultrasonic composited milling system, the kinetic characteristics
of ultrasonic composited milling are discussed, and the stability model of unseparated ultrasonic milling is established.
The semidiscrete method is used to study the stability of ultrasonic composite milling. The numerical analysis was
carried out by using MATLAB, and the stability lobe diagram of ultrasonic milling was obtained. Research shows that the
stability of ordinary milling system can be promoted by the unseparated ultrasonic milling system and the maximum cutting
depth is increased by about 13.8%.The experiment of ultrasonic composited milling was carried out by using titanium alloy
material. The correctness of the theoretical model and the stability lobe diagram was verified by the experiment.At the same
time, the feasibility of using semi discrete method to analyze the stability of ultrasonic composited milling system is verified.
