【Abstract】 Based on the technologies of three dimensional(3D) modeling and dynamic simulation analysis,the Virtual prototype of five-axis computer numerical control(CNC) tool grinder was built. The size of grinding force and changing trend during the five-axis CNC tool grinder working was simulated. Then the validity of the dynamic model was confirmed by the oretical calculation. What’ s more,the influence factors such as wheel speed,grinding depth and feeds on grinding force were researched,which can provide are ference to the design offive-axis CNC tool grinder.更多还原
