To address the non-linear error and tool collision or tool interference introduced by the rotation axis, control strategy of five-axis machining tool axis vector interpolation based on NURBS surface is proposed. By using NURBS surface reconstruction ideas, after node vectors are inverse computed, it is inserted in the U and V-parameter direction of the surface. Then surface control points are anti-calculated, and the data points of shape values on the surface are determined which is tool cutting contacts point. By using normal vector of surface and combining machine tool kinematics analysis results, the rotation angle of the two rotary axes are calculated. And then, the tool axis vector to be interpolated is determined. Simulation results show that the algorithm can effectively improve the accuracy of five-axis CNC machining, and verify the effectiveness and practicality of the algorithm.
