The thermomechanical behavior in tool-chip interface (TCI) is a key factor affecting the cutting performance. However, few investigations have been reported on the thermomechanical behaviors in tool-chip interface in ultrasonic vibration cutting (UVC). In this study, the thermomechanical behaviors in TCI are studied considering the ultrasonic vibration-induced alternation of contact stress and transient characteristics such as shear angle, tool-chip contact length, and flowing stress. The transient model for cutting force incorporating the effect of acoustic softening and transient characteris...
