This paper focuses on the design of the extended branch structure for rapidly and simultaneously interpolating non-uniform rational B-spline (NURBS) surfaces and their partial derivatives on CNC machines. NURBS surfaces are concerned in the applications of molding process. However, the copious and complicated operations usually limit the applications of(More)
This study aims to design a method for implementing the non-uniform rational B-spline (NURBS) curve fitting process on CNC machines for improving the machining quality and efficiency. The conventional CAD/CAM/CNC systems usually induce some machining problems and limit the machining results in real applications. An on-line NURBS curve fitting process(More)
