Ultrasonic assisted grinding is widely used in the field of difficult-to-machine materials. During ultrasonic assisted grinding, the ultrasonic vibration parameters have a major impact on ground surface. Thus, in order to optimize machine parameters before grinding according to simulation results. A new method to model and predict surface topography of the ultrasonic assisted grinding process considering ploughing is proposed. A grinding wheel surface model considering the random distribution of grain is established by supposing the grits are spherical. Based on the geometric mapping relationship between grains and workpiece in ultrasonic assisted grinding, the cutting model of grains considering the real-time cutting depth and ploughing action is presented. The regional approximation calculation method is provided afterward. Consequently, the three-dimensional surface topography of ultrasonic assisted grinding is simulated. At last, this model is verified by the experiment through the surface texture and surface roughness parameters.
