| Abstract Scope |
The free-form bending process is particularly suited for small-batch components of arbitrary three-dimensional shape. Nevertheless, the target geometry is usually input as a discrete set of bending instructions. The derivation of every bending operation from the CAD file is a complex task and can result in a cumbersome decomposition process. On the other hand, a list of sequential bending operations only contains information for each individual bent. In this contribution, an automated tool for turning parametric CAD data into bending instructions and vice-versa is proposed. Regardless of the input type, the target bending line is computed as a NURBS curve, which can in turn be exported as a CAD file or bending table. The tool is validated by two case-studies processing respectively a discrete and parametric description. Finally, the outcome of the presented strategy is demonstrated performing a surface-to-surface comparison between the target CAD component and the obtained bent part. |
