Mar 10, 2016 Self-excited vibration occurs only during grinding, due to grinding parameters, the process, and certain machine characteristics such as natural frequencies of the machine. During grinding, undulations/waves can start to form on either the workpiece or the grinding wheel as fluctuating forces excite a natural frequency on the machine.
