Abstract:

In order to research the 3d topography of ultrasonic grinding workpiece, 3d topography of grinding wheel surface is established. Through analyzing ultrasonic grinding grain trajectory, model of grinding grain workpiece surface cutting process was established. Put forward the path of a large number of random distribution of abrasive cutting workpiece discrete algorithm and minimum height value envelope surface extraction algorithm, implements the establishment of ultrasonic grinding 3d surface topography. , Results of ultrasonic vibration experiment show that the model can effectively predict the surface morphology of ultrasonic grinding, and provides theory basis for ultrasonic grinding process optimization.
