• The growing need for higher precision and productivity in manufacturing industry has lead to an increased interest in computer numerical control (CNC) systems. It is well known fact that the cross-coupling control (CCC) is an effective method for contouring applications. In this paper a new CCC is introduced based on a contour error vector using parametric curve interpolator. The contour error vector is a vector from the actual tool position to the nearest point on the desired path. The contour error vector is the closest error model to the contour error. The simulation results show that the new CCC is more accurate than the conventional CCC for a biaxial motion system. In addition, the experimental results on 3 axis motion system shows that the new CCC is simply applied to 3 axis motions and contouring accuracy is significantly improved.
