1. IntroductionThe contour error control performance for the high-speed and high-precision machining of complex free-form surface parts has a direct and significant impact. Therefore, many scholars have performed in-depth research on contour error control strategies. The control principle can be roughly divided into the following categories [1]: offline methods, interpolator designs, single-axis tracking controllers, cross-coupled control (CCC) methods, coordinate system design, etc.
