In 5-axis machining,the inverse kinematics transformation generates singular positions for which incoherent movements of rotary axes appear.Hence,the machining quality cannot be guaranteed in this area.In this paper,we proposed a method to change the tool path in the machine coordinate by changing the relative configuration between the machine coordinate and the workpiece coordinate so that the tool does not traverse the singular area.Our purpose is illustrated through the example of the machining of a Sshaped workpiece.
