【Abstract】 Based on the nonlinear dynamic model for peripheral milling process, a computer simulation model of dynamic peripheral milling process is developed by using the variable-step numerical integral algorithm and recurrence algorithm. A series of simulation in time domain are conducted to investigate machine tool vibration by inputting different milling process parameters and geometrical parameters of milling cutter. The design of milling process parameters and geometrical parameter of milling cutter is accomplished to obtain the minimum amplitude of relative vibratory displacement in cutter-workpiece system.更多还原
