Paper Abstract

Rounding of polyhedra is an important operation in CAD/CAM. This paper presents a new rounding scheme based on NURBS. Algorithms for generating edge and corner roundings are developed. Rounding surfaces generated are all NURBS surfaces and rounding radius can be precisely controlled. G1 continuity is satisfied between roundings and their base planes and along common edges between edge roundings and corner rounding.
