摘要：
Here, the characteristics of cutting force were studied when the ultrasonic elliptical vibration cutting (UEVC) method was used to process TC4 titanium alloy. The transient cutting processes of titanium alloy with UEVC method were numerically simulated based on the force-thermal coupled model in the finite element (FE) software ABAQUS under different cutting depths and cutting speeds, and extract the main cutting forces. The main cutting forces of UEVC were compared with those of the conventional cutting (CC), and the data processing was done for them to analyze differences between the two main cutting forces and their variation. The study and analysis showed that Under UEVC, the reduction rate of cutting forces decreases with increase in cutting depth, and increases with increase in cutting speed. Finally, tests were conducted to verify the simulation results, and the test results agreed well with those of simulation. The results provided a reference for choosing cutting amount during titanium alloy processed with UEVC. © 2019, Editorial Office of Journal of Vibration and Shock. All right reserved.
