The application of metal cutting fluids is an integral part of industrial machining operations. Minimum quantity lubrication (MQL) is the latest form of cutting fluid application method currently used by several manufacturing organizations. This book consolidates all the available knowledge in terms of the application of different processes as well as materials in a concise fashion in one reference resource. Sustainable Machining Using MQL Application of Cutting Fluids offers a detailed discussion of the MQL mechanism in cutting fluid applications. It highlights the influence of MQL parameters on different workpiece materials and provides sound explanations along with photographs for all technical reasonings. The book presents the usage of both micro and nano cutting fluids in machining for sustainability while it also captures the knowledge in the field including the recent research outputs, as it illustrates a comprehensive coverage of MQL practical application. This book should be on the bookshelf of industrial engineers, those working in production and manufacturing, process designers, tool material designers, cutting tool designers, and quality specialists. Researchers, senior undergraduate students, and graduate students will also find this book full of very helpful reference information.

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.

Providing environmentally friendly conditions and optimizing energy consumption are two essential requirements in order to achieve sustainable machining processes. One of the major sustainable machining concerns is the implementation of cutting fluids due to its significant impact on the machining quality characteristics. In addition, several economic, environmental, and health problems take place due to the inappropriate application of cutting fluids, therefore, previous research has introduced advanced cutting fluids technologies in order to optimize the cutting fluids usage during machining. However, there are still issues related to machining difficult-to-cut materials that have not been addressed and need to be improved. These materials have superior characteristics such as high strength to weight ratio, corrosion resistance, temperature resistance, and chemical stability, allowing them to be materials of choice in the aerospace, automotive, oil and gas, and bio-medical industries. Despite their desired characteristics, the wide spread applications of these materials has been compromised by several difficulties that arise during machining. Flood cooling is a typical cooling strategy used in industry to dissipate the high heat generated during machining difficult-to-cut materials; however, the use of flood coolant has raised environmental and health concerns which call for different alternatives. Minimum Quantity Lubricant (MQL) has been successfully utilized as an acceptable coolant strategy; however, its potential to dissipate heat is much lower than the one achieved by flood coolant. One of the best techniques to enhance MQL heat capacity is the application of nano-cutting fluids as they offer significant enhancement in the tribological and heat transfer characteristics. The main objective of the proposed research is to fully investigate and understand the influence and role of dispersed multi-walled carbon nano-tubes (MWCNTs) into vegetable oil by implementing the minimum quantity lubrication (MQL) technique during turning Ti-6Al-4V titanium alloy and Inconel 718. The Investigations include study of the energy consumption, tool wear behavior, chip morphology, and surface quality when using nano-cutting fluids based MQL. The study revealed that nano-fluid based MQL improves the tool performance and proves clear advantage over the traditional/classical MQL. In order to provide a solid physical understanding of the studied cutting processes using MQL-nano-fluids, the tribological aspects of the process and heat transfer mechanisms have been analyzed and investigated. The study presented a comparative performance analysis between MWCNTs and aluminum oxide (Al2O3) nano-cutting fluids. Additionally, an integrated finite element (FE) model has been developed in order to simulate the thermal and frictional effects of the MQL-nano-fluid to study various unique cutting aspects such as generated cutting temperature and residual stresses. Furthermore, a general and detailed assessment model is developed and used to assess the sustainability of machining processes. Energy consumption, machining costs, waste management, environmental impact, and personal health and safety have been used to express the overall sustainability assessment index. It should be stated that the model predictions agree with the experimental findings. As such, the developed model offers a valuable tool to optimize the sustainability aspects of machining process.

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.
