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.
