Abstract: Five axis machining is a mode of NC machine tool processing, with high efficiency, high precision, and workpiece clamping at one time. It is suitable for processing modern moulds such as automobile parts and aircraft structural parts. But the motion of the rotating axis in five axis machining causes singularity, nonlinearity and other problems, which affect the quality of the part surface. Therefore, the causes of a series of problems were analyzed, and the optimization method of five axis machining singular problem was proposed and discussed.
Key words: five-axis machining; singular problem; nonlinear problem; tool direction, rotary motion
