Review: application of green manufacturing processes in precision machining of automotive components

Green manufacturing technology is a key pathway for achieving sustainable development in modern manufacturing particularly in the precision machining of automotive components. This study provides a comprehensive overview of the core elements of green manufacturing, focusing on four key aspects: material selection, energy efficiency optimization, waste minimization, and recycling and remanufacturing. The review also examines the application of advanced technologies, such as laser machining and digital twins, in the green manufacturing process, highlighting their effectiveness through case studies of transmission gears and engine components. The results demonstrate that green manufacturing processes can significantly reduce energy consumption and waste generation, while improving material utilization and production efficiency. However, the high cost of equipment and the steep technical requirements remain significant barriers to widespread adoption. Looking forward, advancements in intelligence and digitalization are expected to drive further progress in green manufacturing, supporting the automotive industry’s transition to a low-carbon future.
