Book Description
The purpose of this monograph is to characterize and describe the quality of machined wood surfaces, whereas particular attention is given to the utility and to aesthetical values in product design. The approach employed by the authors involves an introductory overview and is then organized in three parts: first, the book deals with factors influencing surface stability, the second part describes the color and gloss properties of wood surfaces with many practical applications, and the third part covers roughness properties of surfaces related to machining. This is a highly informative and carefully presented book, providing valuable insight for both research experts and practitioners with an interest in machined wood surfaces.

Book Description
The market for durable products using modified wood has increased substantially during the last few years. This is partly because of the restriction on the use of toxic preservatives due to environmental concerns, and to lower maintenance cost and time. Furthermore, as sustainability becomes a greater concern, the environmental impact of construction and interior materials is factored in planning by considering the whole life cycle and embodied energy of the materials used. Wood is modified to improve its intrinsic properties, enhance the range of applications of timber, and to acquire the form and functionality desired by engineers without calling the environmental friendliness into question. Wood modification processes are at various stages of development, and the challenges faced in scaling up to industrial applications differ. The aim of this book is to put together the key elements of the changes of wood constituents and the related changes in wood properties of modified wood. Further, a selection of the principal technologies implemented in wood modification are presented. This work is intended for researchers, professionals of timber construction, as well as students studying the science of materials, civil engineering and architecture. This work is not exhaustive, but intends to deliver an outline of the scientific disciplines necessary to apprehend the technologies of wood modification and its behavior during treatment, as well as during its use.

Book Description
Over the past two decades U.S. lumber imports from the tropics have increased fourfold. Plywood trade, mostly from Asian sources, has soared forty-fold and now equals our domestic production. Log imports, though, have decreased drastically from about 100 million board feet (log scale) in the 1950's to 30 million currently. Much of the world timber trade now is in the form of processed material. Many more tropical wood species and species groupings are being made available to U.S. processors. Most of these have been well known for many years on the European markets. This interest in supplemental supplies from overseas is in both softwoods and hardwoods. An extensive foreign literature has described the properties and uses of tropical woods, but much of it is no longer readily available. In this country the U.S. Forest Products Laboratory, over the years, issued 'Information Leaflets' or 'Foreign Wood Series' reports on some species of importance. But many of these are now out of print. The most recent comprehensive document, 'Properties of Imported Tropical Woods, ' contained a description of about 100 tropical genera.

Book Description
Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.

Book Description
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.

Book Description
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.

Book Description
Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.
