The thesis titled "Design, Functional and Functional Development of a Wood Sawing Machine" addresses the issues of wood processing and the application of innovative engineering solutions for this purpose. The introductory chapter discusses the preparation, storage, and use of wood, with emphasis on wood processing machines, particularly wood sawing machines. The examination is conducted through the context of the history of wood processing machines, providing the reader with a clear picture of the evolution of machines and technologies over time. The work then focuses on a review of existing design solutions for wood sawing machines, including tractor-powered, automotive towed, and self-propelled machines. An analysis and definition of the functional structure of a new wood sawing machine is made, setting the framework for further concept development. Next, three different machine concepts are elaborated, using a morphological matrix to solve partial functions. Each concept is analyzed and evaluated using the AHP method, allowing for structured and objective evaluation. Analytical/numerical calculations of the structural elements of the new machine are performed to ensure its functionality, including the necessary power for the operation of the machine, belt speed, selection and calculation of bearings, and shaft loads. The final chapter shows the assembly of the product generated using a CAD system, detailing the geometric relationships between the structural elements.
