The text discusses both theoretical and technological aspects of the Industry 4.0–based manufacturing processes. It covers important topics such as additive manufacturing, laser-based manufacturing processes, electromagnetic welding and joining processes, green manufacturing processes, and friction welding processes. A paradigm shift can be achieved from mass production to customized production by incorporating the Industry 4.0 manufacturing processes. The modern advanced sustainable and green manufacturing processes enable the production of products on the concept of just-in-time. Sustainable financial and environmental benefits can be achieved by incorporating the industry 4.0 manufacturing processes. “Smart Manufacturing Processes for Sustainable Development in Industry 4.0”contains 12 chapters that focus on the present status and research prospects related to the manufacturing processes of the fourth industrial revolution. These manufacturing processes are the real foundation of Industry 4.0 in terms of the intelligentization and digitalization of the manufacturing processes. In this book, both theoretical and technological aspects of the Industry 4.0–based manufacturing processes have been discussed. The main topics discussed in the proposed book are additive manufacturing, laser-based manufacturing processes, electromagnetic welding and joining processes, green manufacturing processes, and friction welding processes.
