In order to improve the processing quality of the ultrasonic vibration cutting process and reduce the surface roughness of the workpiece, based on the Response Surface Methodology (RSM), the second-order response model of 45 steel ultrasonic vibration cutting is established. The 45 steel ultrasonic vibration cutting roughness model is fitted by the central composite experiment. The reliability of the model was verified by the significance analysis based on analysis of variance and the validity analysis based on residual graph. Finally, the 3D response surface map of the surface roughness of the workpiece was cut by ultrasonic vibration, and the influence of various process parameters on the surface roughness was analyzed. The suitable cutting amount combination was selected: the spindle speed is 70.95m/min, the cutting speed is 0.11m/min, while the feed rate is 0.95mm/r and the ultrasonic amplitude is 26.80mm.
