Wood product design is a specialized field that plans and determines the function, form, structure, and manufacturing process of products primarily made from wood. It requires a deep understanding of the characteristics unique to wood as a natural material, such as its anisotropic strength, hygroscopicity, and grain, and the ability to balance aesthetics, functionality, and workability. Its applications range widely, including furniture, building materials, interior materials, musical instruments, and crafts. In recent years, its use as a structural material, such as CLT (Cross-Laminated Timber), has also expanded. Representative processing methods include cutting (including NC machining), sanding, joining (wood joinery, adhesion), bending, and surface treatment. Comprehensive engineering, considering everything from material selection and manufacturing processes to sustainability, is crucial.
