This book presents select proceedings of the National Conference on Sustainable Machining Strategies for Better Performance (SMSBP 2020). It examines a range of machining strategies that helps to improve sustainability in machining processes. The focus is to improve competition, reduce costs, comply with environmental regulations and address environmental concerns. The topics covered include machining of difficult-to-machine materials, developments in new cutting tool materials, modern cooling methods, use of advanced machining technologies, lubrication strategies like MQL, cryogenic cooling, use of cold compressed air, adoption of hybrid cooling strategies, hybrid machining strategies, machining of special materials including elastomers and surface integrity studies in use of cryogenic machining. The book presents the latest research developments in the domain of sustainable machining which can improve the machining practice adopted by researchers, professionals and industries. The book will be a valuable reference for  researchers, professionals and people from machining and material-related industries who are interested in adopting sustainable machining strategies.
