| summary |
Computational and robotic approaches for bending wood include cutting kerfs and slits that generates flexibility in the wood or using external fixtures to keep the wood bent while in tension. In both cases, the bent configuration is maintained using glue or external fixtures, making it challenging to unbend the wood back to its straight configuration.
The paper presents a novel method for parametric and reversible solid wood bending inspired by kerfing and Active Bending. The aim is to create a computational method in which, for any curve that consists of arcs and straight lines, a cut pattern is generated that allows the bending of a solid wood beam to match the input curve. The suggested approach is based on splitting an arc into two parts, connected by a thin bar along the grain direction. The bar is elastic and allows for manual bending. While bending, the precise CNC cutting of the arcs forces the wood to take the intended bending shape while maintaining tension. A bowtie inlay locks the bending in place. Once the locking is removed, the wood may be unbent. The research explores the limitation of the suggested method in terms of the possible bent radii and conducts compression tests to evaluate the strength of the bentwood. Two main advantages of the suggested approach are demonstrated. The first is creating curved profiles out of timber wood, which is limited in width. The second advantage is material efficiency when cutting curved profiles from plywood panels. Our computational bending method enables designers to prototype and construct DIY furniture and temporary structures with a simple assembly. |
