This new edition of Gear-Cutting Tools has been updated with revised chapters and illustrations as well as additional, new material with the aim to provide a systematic and comprehensive discussion on modern designs, kinematics, and cutting geometry of gear-cutting tools.
This book presents the DG/K-based method of surface generation—a practical mathematical method for designing gearcutting tools with optimal parameters. The text addresses the evolution of gear-cutting tools and scientific classification for all types of gear machining meshes before discussing optimal cutting tool designs. Designs currently used and those being planned are covered, and the approach allows for the development of scientific predictions and optimal designs. Solutions appear in analytical form and/or graphical form, with a wealth of new figures added, and new appendices offer additional data for readers.
This is an essential reading for engineers who work in the field of gear-cutting, especially those involved in the manufacturing of autos, aircraft, agriculture machines, and metal-cutting machines. This book would also be relevant to various mechanical engineering courses for graduate students, such as machine elements, machine and mechanism science, and theory of machines and mechanisms.
