The contour following task of a multi-axis servo system is one of the most important applications of modern Computer Numerical Control (CNC) machine tools, and is widely seen in many types of CNC machining. Hence, the reduction of contour error occurring in the contour following process is paramount and deserves more comprehensive investigation. In general, the calculation of precise contour error...
Generally, the shapes of most precision manufacturing and machining products are described by complex free-form curves/surface, thus it is essential that modern CNC (Computer Numerical Control) machine tools are equipped with parametric free-form curve interpolators. In many application scenarios, a CNC machine tool is required to perform free-form contour following tasks. In order to design an effective...
