This new edition draws upon the fundamentals of abrasive machining processes and the science of tribology to understand, predict, and improve abrasive machining processes. Each of the main elements of the abrasive machining system is looked at alongside the tribological factors that control the efficiency and quality of the processes described. The new edition has been updated to include a variety of industrial applications. Grinding and conditioning of grinding tools are dealt with in particular detail, and solutions are proposed for many of the most commonly experienced industrial problems, such as poor accuracy, poor surface quality, rapid tool wear, vibrations, workpiece burn, and high process costs. The entire book has been rewritten and restructured, with ten completely new chapters. Other new features include:

Extensive explanations of the main abrasive machining processes such as grinding (including reciprocating and creep-feed grinding, high-speed high-efficiency deep grinding, external and internal cylindrical grinding, and centerless grinding), honing, superfinishing, lapping, polishing, and finishing Discussions of the new classes of abrasives, abrasive tools, and bonding materials New case studies and troubleshooting on the most common grinding practices New coverage on grinding tool conditioning, mechanical dressing, and nonmechanical dressing processes Detailed explanations of the effects of process input parameters (such as cutting parameters, workpiece material and geometry, and abrasive tools) on process characteristics, workpiece quality, tool wear, and process parameters (such as cutting forces and temperature as well as achievable material removal rate) Updated topics regarding process fluids for abrasive machining and fluid delivery

Edited by experts, one of whom developed the technology, Electrolytic In-Process Dressing (ELID) Technologies: Fundamentals and Applications provides an overview of ELID processes with correlations between the main parameters, describes ELID operations, and illustrates the concepts with case studies. The book’s authoritative coverage of major concepts and applications of this emerging technology makes it a definitive reference.The book delineates the fundamentals, the chemistry and physics, and the hardware required by the process, then explores the application of ELID to different configurations of grinding. It discusses ELID grinding methods, lapping/grinding process, honing, and an original method of ELID grinding of free forms surfaces using an original design. The book also provides case studies in areas such as: Nano ultra-precision ELID and the latest developments in ELID nano-grindingGlass ceramic mirrors, small lens, and large scale opticsNew concept of micro-workshop, where all the machines tools and measurement devices are table-top machines with high accuracySuccessful applications of ELID technology in the optics, semiconductor, mold and die, and micro-tools industriesSurface modifications as a future method for obtaining complex modifications of surfaces by using ELID in combination with other methodsArguably the first comprehensive review of this emerging technology, this book combines information drawn from experts and the literature to provide a practical reference for the field. The editors have put together a resource that anticipates many of the questions that will arise from the investigation of ELID methods and applications.

This book draws upon the science of tribology to understand, predict and improve abrasive machining processes. Pulling together information on how abrasives work, the authors, who are renowned experts in abrasive technology, demonstrate how tribology can be applied as a tool to improve abrasive machining processes.

Each of the main elements of the abrasive machining system are looked at, and the tribological factors that control the efficiency and quality of the processes are described. Since grinding is by far the most commonly employed abrasive machining process, it is dealt with in particular detail.

Solutions are posed to many of the most commonly experienced industrial problems, such as poor accuracy, poor surface quality, rapid wheel wear, vibrations, work-piece burn and high process costs. This practical approach makes this book an essential tool for practicing engineers.

Uses the science of tribology to improve understanding and of abrasive machining processes in order to increase performance, productivity and surface quality of final products A comprehensive reference on how abrasives work, covering kinematics, heat transfer, thermal stresses, molecular dynamics, fluids and the tribology of lubricants Authoritative and ground-breaking in its first edition, the 2nd edition includes 30% new and updated material, including new topics such as CMP (Chemical Mechanical Polishing) and precision machining for micro-and nano-scale applications
