Rational Cubic B-Spline Interpolation and Its Applications in Computer Aided Geometric Design
… that the weights and the control points provide, NURBS have recently become very popular tools for the design of curves and surfaces. If the weights are positive then the NURB will lie in the convex hull of its control points and will not possess singularities. Thus it is desirable to have …

Reducing Curvature in Complex Tool Paths by Deviating from CAM-Produced Tool Paths Within a Tolerance Band
This thesis develops an algorithm to decrease high-curvature sections in tool paths for complex parts to achieve shorter machining times resulting in higher production rates. In the research sample cases, the algorithm decreased machining times by 1% to 9% for design-induced sections of high …
