Abstract
As the next-generation manufacturing system, intelligent manufacturing enables better quality, higher productivity, lower cost, and increased manufacturing flexibility. The concept of sustainability is receiving increasing attention, and sustainable manufacturing is evolving. The digital twin is an emerging technology used in intelligent manufacturing that can grasp the state of intelligent manufacturing systems in real-time and predict system failures. Sustainable intelligent manufacturing based on a digital twin has advantages in practical applications. To fully understand the intelligent manufacturing that provides the digital twin, this study reviews both technologies and discusses the sustainability of intelligent manufacturing. Firstly, the relevant content of intelligent manufacturing, including intelligent manufacturing equipment, systems, and services, is analyzed. In addition, the sustainability of intelligent manufacturing is discussed. Subsequently, a digital twin and its application are introduced along with the development of intelligent manufacturing based on the digital twin technology. Finally, combined with the current status, the future development direction of intelligent manufacturing is presented.

Summary
As an upgrade to manufacturing industries, Industry 4.0 proposed next-generation intelligent manufacturing to achieve high adaptability, rapid design changes, digital information technology, and more flexible technical workforce training. The concept and application of a digital twin are introduced along with the application of the digital twin from three aspects: product design, manufacturing, and product service. Digital twindriven sustainable intelligent manufacturing is introduced from three aspects: intelligent manufacturing equipment, system, and service (see Fig. 1). The development trend of intelligent manufacturing is summarized from three aspects: framework, enabling technology and application of sustainable intelligent manufacturing. The framework of sustainable intelligent manufacturing includes sustainable intelligent design, comprehensive sustainability, humanmachine collaboration, sustainable intelligent manufacturing for product life cycle, across enterprise value chain, for product environmental footprint, and sustainable intelligent manufacturing equipment, system, and service. The enabling technology of sustainable intelligent manufacturing includes digital twin-based big data-driven, artificial intelligence-driven, and Internet of Things (IoTs)-driven sustainable intelligent manufacturing
