【Abstract】 On the basis of establishing of the dynamic model of the cylindrical grinding process, this paper demonstrates the relationship between the contact stiffness of the grinding wheel and workpiece and the chatter frequency of the workpiece by matrix perturbation theory, and probes into the relationship between the radial grinding force and the contact stiffness,and between the rotational speed of the grinding wheel and the radial grinding force. It is obtained that the rotational speed of the grinding wheel and the chatter frequency of the workpiece has a corresponding relation. When the rotationalspeed of the grinding wheel is changed periodically, the chatter frequency of the workpiece varies periodically,so that the growth of the chatter of the workpiece is suppressed.更多还原
