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.

This book examines a topic which is an indispensable part of any production line in the wood industry: the extraction, separation, handling of dust and chips, ensuring clean air in the workrooms, and avoiding health, fire and explosion risks. All scientific backgrounds of these problems are not fully known today, and efforts should be made to fill this gap. The work contains significant new derivations and calculation methods and experimental results to support design and evaluation methods such as particle size distributions depending on wood species and machining, terminal velocity of small wood particles, aerodynamics of suction hoods, a detailed analysis of particle separation in cyclones, selection and evaluation of separation efficiency for appropriate filter selection, energy consumption and transportation efficiency of pneumatic conveying, a comprehensive theory of transport ventilators. Several new details of dust explosion are also included. The calculation methods, practical solutions and recommendations are supported by physically well-established explanations providing long-lasting knowledge.
