【Abstract】 In this paper, the virtual model of the three axes milling CNC and the simplest coordinatesystem are established with Pro/E. The friction dynamic model for general virtual three axesCNC is built based on the analysis of the machine structure. Through the dynamic simulationof circle motion for the three axes CNC XH-714 by means of ADAMS software, the nonlinearaffection of the friction to the machining accuracy is confirmed.更多还原
