چکیده

The effective reuse of freeform features represented by NURBS is still an open issue. In this paper, a novel approach to the reuse of freeform features with NURBS representation is proposed. Firstly, the conditions for preserving differential properties of reused freeform features are derived, and a reuse-oriented representation of freeform features is put forward. Based on them, a reuse algorithm of freeform features is developed, which adopts Poisson equation, knots insertion and degree elevation to achieve the preservation of the differential geometry properties and the adaptability. The approach is implemented and some examples are given. 2008 Elsevier B.V. All rights reserved.

Techniques for Freeform Feature Modelling

Research on regular-shaped features has been going on for a relatively long period now. However, more complicated, freeform features are demanded by product designers. Freeform shapes are mostly represented by low-level entities, such as Bézier, B-Spline and NURBS patches. Such low-level entities are not intuitive enough for designers to work with directly. Freeform features provide a high-leve...

Direct slicing of STEP based NURBS models for layered manufacturing

Direct slicing of CAD models to generate process planning instructions for solid freeform fabrication may overcome inherent disadvantages of using stereolithography format in terms of the process accuracy, ease of file management, and incorporation of multiple materials. This paper will present the results of our development of a direct slicing algorithm for layered freeform fabrication. The di...

One-sided offset approximation of freeform curves for interference-free NURBS machining

Generating valid tool path curves in NURBS form is important in realizing an efficient NURBS machining. In this paper, a method for computing one-sided offset approximations of freeform curves with NURBS format as tool paths is presented. The approach first uses line segments to approximate the progenitor curve with one-sided deviations. Based on the obtained line approximating curve and its of...

NURBS-compatible subdivision surfaces

Two main technologies are available to design and represent freeform surfaces: NonUniform Rational B-Splines (NURBS) and subdivision surfaces. Both representations are built on uniform B-splines, but they extend this foundation in incompatible ways, and different industries have therefore established a preference for one representation over the other. NURBS are the dominant standard for Compute...

NURBS surface fitting using orthogonal coordinate transform for rapid product development

Constructing a CAD model from a physical model plays a key role in some rapid product development processes. Presented in the paper is a method of ®tting NURBS surfaces for rotational freeform shapes: (1) cloud-of-points data (COP-data) representing a rotational freeform shape are transformed into an orthogonal coordinate system, (2) a single-valued B-spline surface is ®tted to the transformed ...
