This study investigates the shape of the longitudinal joints in hardwood panels, inspired from veneer joints commonly used in the industry. The design of these joints is tailored to facilitate creative and flexible compositions. The joints adopt a mathematical description using splines, serving a good technological purpose for the wood processing. Employing laser cutting technology, the shapes are precisely crafted by a laser beam on the hardwood panels. After the process, the joints undergo a visual inspection, the material loss due to the technology is calculated, and other parameters are determined. Additionally, significant characteristics relevant to practical applications, such as joint fit, shape of accuracy, and aesthetics, are assessed. To enhance the understanding of the mechanical interactions, finite element analysis (FEA) is performed to model the mechanical contacts within the joints. A primary motivation for this research is the efficient utilization of residual wood materials. This approach aims to extend the life of the available raw materials within the value chain, contributing to sustainability goals.
