| Abstract: | The cutting force model of the ball end milling cutter was built,basing on its geometry model,considering effective cross-cutting area of the cutting edge and regenerative effect.The dynamic model of the ball end milling cutter was presented by mode testing and parameter identifying.Runge-Kutta method was employed to simulate the milling stability of the ball end milling cutter in Matlab.The simulations show that the model can be used to describe the dynamic characteristics,such as stability and vibration.They are benefit to the optimal designs of milling process and the testing machine. |
