A real-time tool path generation and control method of five-axis CNC machine tool is proposed. The space path of five-axis CNC machine tool is described by gridding surface. The position,direction and different movement parameters of the tool are calculated and controlled within the sampling period,and the curve model was established by the calculated data. The generated order was executed by the inverse kinematics model within the specified sampling time. The superiority and universali-ty of the proposed method were verified by simulation instance to a set of tool path.
