Wood is one of the most valuable materials for mankind, and since our earliest days wood materials have been widely used. Today we have modern woodworking machine and tools; however, the raw wood materials available are continuously declining. Therefore we are forced to use this precious material more economically, reducing waste wherever possible. This new textbook on the “Mechanics of Wood Machining” combines the quantitative, mathematical analysis of the mechanisms of wood processing with practical recommendations and solutions. Bringing together materials from many sources, the book contains new theoretical and experimental approaches and offers a clear and systematic overview of the theory of wood cutting, thermal loading in wood-cutting tools, dynamic behaviour of tool and work piece, optimum choice of operational parameters and energy consumption, the wear process of the tools, and the general regularities of wood surface roughness. Diagrams are provided for the quick estimation of various process parameters. This book will be useful for scientists, graduate and postgraduate students, and practising engineers seeking a deeper understanding of physical phenomena associated with real woodworking processes.

The new edition of this textbook, while largely retaining the proven chapter structure of the previous editions, combines the quantitative, mathematical analysis of the mechanisms of wood processing with practical recommendations and solutions. It presents new theoretical and experimental approaches and offers a clear and systematic overview of the theory of wood cutting, thermal loading in wood-cutting tools, optimum choice of operational parameters, dynamic behavior of tool and workpiece, stability problems in wood machining, energy requirements, the wear process of tools and a unique analysis of surface roughness. In general, diagrams are provided to help quickly estimate various process parameters. As a modern and powerful tool, the process optimization procedure is also included, and amply demonstrated in worked-out examples. In this edition, new and updated material has been added in many sections: roughly a third of the book has been rewritten and a quarter of the figures are new. In addition, many figures have been revised for clarity. The authors are confident that this revised and expanded edition will continue to meet the needs of all those working in the field of wood machining.

Wood as an engineering material can be technically defined “as a hygroscopic, orthotropic, biological, and permeable material having extreme chemical diversity and physical complexity with structures, that vary extensively in their shape, size, properties and function”. Therefore, using wood to its best advantage and most efficiency in engineering applications, specific characteristics or chemical, physical and mechanical properties must be considered. The products are divided into two classes, solid wood and composite wood products. Solid wood includes shipbuilding, bridges, flooring, mine timbers, etc. Composite wood products include insulation board, plywood, oriented strand board, hardboard and particle board. In recent years, the machining of wood products has acquired great importance due the short supply of wood and increasing environmental awareness among users and manufacturers. The optimization of the machining process centers around the mechanism of chip formation, tool wear, workpiece surface quality, crack initiation and propagation of different types of wood. Other factors are also humidity, temperature, static preloads, and vibrations that can affect the wood during the machining process. The book provides some fundamentals and recent research advances on machining wood and wood products.
