The process of high-speed dry gear milling by single tooth flying cutter is discussed taking these factors such as the regenerate domino effect of milling liberation

non-continuous cutting and cutting thickness into account

the kinetics’ model of this cutting process is set up

digital simulation based on Matlab/Simulink is carried out

the milling vibration result under the condition of high-speed dry gear milling by single tooth flying cutter is acquitted.Contrasting this result with other experimental or research result

it indicates that the model is exact.The model can accurately reflectes the relationship between the dynamic cutting force and various kinds of cutting parameters as well as the state of the tool’s vibration

relatively reflects the process of cutting liberation factually.The theoretical foundation for further research in this field is laid.
