"Hundreds of manufacturing operations are finding that methods and tools that support near-dry machining, or minimum quantity lubrication (MQL), provide numerous benefits in both metal cutting and forming operations. This program surveys four very-different manufacturers; Ford Motor Company, Amerimax, Advanced Mold and World Machinary and Saws System Co., that use MQL to apply only the minimum amount of lubricant needed for each job. Each of these companies had once relied on traditional flood-coolant methods that supply large amounts of fluids to the machining process - creating high handling, cleaning, and disposal costs, as well as hazards to plant workers' skin and lungs"--Container.
The future of manufacturing companies depends largely on their ability to adapt to swiftly changing global conditions. These are exemplified by international com- tition, rapidly growing intercommunication and the increased significance of en- ronmental issues [KLOC98a, ENGE02]. Precision machining with geometrically undefined cutting edges represents a key production engineering technology with high efficiency, security and machining quality. DIN norm 8589 subsumes within the group “machining with geometrically - defined cutting edges” the following material removal manufacturing processes: grinding, honing, lapping, free abrasive grinding and abrasive blast cutting. - chining is carried out in these production methods by means of more or less - regularly formed grains composed of hard substances brought into contact with the material. Of all methods understood as machining with geometrically undefined cutting edges, only grinding, honing and lapping can, strictly speaking, be considered p- cision machining. Free abrasive grinding and abrasive blast cutting, also treated in this book, represent a special group, as they generally cannot bring about geom- rical change in the material.
In today’s modern world, the manufacturing industry is embracing an energy-efficient initiative and adopting green techniques. One aspect that has failed to adopt this scheme is flood grinding. Current flood grinding methods increase the treatment cost of grinding fluid and waste large quantities. In order to remain sustainable and efficient, in-depth research is necessary to study green grinding technologies that can ensure machining precision and surface quality of workpiece and reduce grinding fluid-induced environmental pollution. Enhanced Heat Transfer Mechanism of Nanofluid MQL Cooling Grinding provides emerging research exploring the theoretical and practical aspects of nanofluid lubrication and its application within grinding flow and green manufacturing. Featuring coverage on a broad range of topics such as airflow distribution, morphology analysis, and lubrication performance, this book is ideally designed for mechanical professionals, engineers, manufacturers, researchers, scientists, academicians, and students seeking current research on clean and low-carbon precision machining methods.

Environment-Friendly Machining provides an in-depth overview of environmentally-friendly machining processes, covering numerous different types of machining in order to identify which practice is the most environmentally sustainable. The book discusses three systems at length: machining with minimal cutting fluid, air-cooled machining and dry machining. Also covered is a way to conserve energy during machining processes, along with useful data and detailed descriptions for developing and utilizing the most efficient modern machining tools. Researchers and engineers looking for sustainable machining solutions will find Environment-Friendly Machining to be a useful volume.
Machining is one of the most important manufacturing processes. Parts manufactured by other processes often require further operations before the product is ready for application. “Machining: Fundamentals and Recent Advances” is divided into two parts. Part I explains the fundamentals of machining, with special emphasis on three important aspects: mechanics of machining, tools, and work-piece integrity. Part II is dedicated to recent advances in machining, including: machining of hard materials, machining of metal matrix composites, drilling polymeric matrix composites, ecological machining (minimal quantity of lubrication), high-speed machining (sculptured surfaces), grinding technology and new grinding wheels, micro- and nano-machining, non-traditional machining processes, and intelligent machining (computational methods and optimization). Advanced students, researchers and professionals interested or involved in modern manufacturing engineering will find the book a useful reference.
Advanced Machining Processes of Metallic Materials: Theory, Modelling and Applications, Second Edition, explores the metal cutting processes with regard to theory and industrial practice. Structured into three parts, the first section provides information on the fundamentals of machining, while the second and third parts include an overview of the effects of the theoretical and experimental considerations in high-level machining technology and a summary of production outputs related to part quality. In particular, topics discussed include: modern tool materials, mechanical, thermal and tribological aspects of machining, computer simulation of various process phenomena, chip control, monitoring of the cutting state, progressive and hybrid machining operations, as well as practical ways for improving machinability and generation and modeling of surface integrity.

This book presents a collection of examples illustrating the resent research advances in the machining of titanium alloys. These materials have excellent strength and fracture toughness as well as low density and good corrosion resistance; however, machinability is still poor due to their low thermal conductivity and high chemical reactivity with cutting tool materials. This book presents solutions to enhance machinability in titanium-based alloys and serves as a useful reference to professionals and researchers in aerospace, automotive and biomedical fields.
