Abstract
In order to improve the machining quality, improve the machining efficiency and reduce the machining cost of micro-grinding, a nonlinear dynamics micro model was established based on the macro grinding dynamics model, and the nonlinear dynamics equation of micro-grinding was also deduced. The nonlinear dynamic equation was approximated by third order to increase the grinding system parameters. According to the characteristics of the system, the corresponding two-parameter limiting stability lobe diagram is obtained and the stability is predicted. The main parameters include grinding wheel speed, workpiece speed, feed speed, equivalent grinding wheel length and diameter and so on. Finally, the corresponding time domain response graphs and eigenvalue location graphs based on the limit stability graphs of different parameters were drawn to verify the correctness of the stability prediction.
