【Abstract】 Based on the kinematic analysis of the cutting edge in longitudinal-torsional combined ultrasonic vibration milling, the chip cross-sectional area and relative slip velocity between the tool and the workpiece in the milling process are calculated. The friction force model and the chip deformation force model are established, and then the comprehensive mathematical model of longitudinal-torsional combined ultrasonic vibration milling force is constructed.Longitudinal-torsional combined acoustics system of ultrasonic vibration is developed andthe platform of longitudinal-torsional combined ultrasonic vibration milling is built. The single factor method is used to carry out the experiment. The experimental results show that the simulation value of the milling force mathematical model is in good agreement with the measured values, which verifies the correctness of the model.更多还原
