Abstract: In order to form stable micro texture on the surface of 7075 aluminum alloy and improve its
services performance during metal cutting, the micro texture ultrasonic milling process is proposed. Therefore,
based on the principle of motion synthesis, the characteristics of tool tip motion trajectory and the micro
morphology of the work-piece surface were obtained. Then, based on the equivalent circuit principle and
transmission matrix method, the frequency equation of the longitudinal-torsional composite ultrasonic milling
system was established and the accurate numerical solution was obtained by the Newton iteration method，
and the longitudinal-torsional composite vibration was realized. After that, the model analysis and dynamic
characteristics analysis of ultrasonic vibration system were carried out by the finite element software. Finally,
the vibration test, cutting force test and the machining test of the micro texture longitudinal-torsional composite
ultrasonic milling system were carried out. The results show that the fishscale texture formed on the surface
of the workpiece could change its wettability.
