Abstract：In order to reduce the shock of machine motion axis in surface numerical control(NC) machining,the method of using machine tool with redundant degree of freedom(DOF) in high speedfeed complex surface machining is proposed in this paper.The motion axis of redundant degree of freedom in numerical control is added to decompose the movement of machine tool axis with greater impact.In this paper,the decomposition principle of the movement of machine tool axis under redundant DOF is analyzed so as to provide the method of synthesized machining path calculation and error determination under the condition of redundant degree of freedom.Finally,the result of calculation example has verified the effectiveness of the idea and method proposed in this paper.
