Abstract

En 中文

• A surface-smoothed toolpath as novel surface-level smoothing paradigm. • A UV-Z scalar B-spline enables efficient evaluation of 3D surfaces. • SST guarantees C2 continuity and neighboring consistency. • An SST-oriented interpolation scheme for feedrate planning. • Experiments show SST significantly improves machining surface quality.
