“…In recent years, the application of DT in machine tools has made achievements in many aspects. For the DT-driven machine tool framework, Hänel et al [15] introduced a competitiondriven digital transformation in the machining sector, in which the creation of a DT for machining processes is approached by using a basic DT structure; Zhao et al [16] proposed an advanced DT system framework for CNC machine tools and discussed the key factors that made the DT system more practical; Vishnu et al [17] proposed a digital twin framework for NC machining processes, which allows simulation, prediction, and optimization of key performance indicators using the historical and real-time machining data during process planning and machining phases, respectively. For thin-walled parts manufacturing, Zhu et al [18] presented a DT-driven thin-walled part manufacturing framework to allow the machine operator to manage the product changes, and make the start-up phases faster and more accurate.…”

Thin-walled parts are widely used in the aerospace industry, where the milling deformation of the parts caused by their thin-walled draping and extremely large size ratio characteristics as well as high material removal rate has been the most common quality issue that greatly influences the assembly performance and operation safety of aerospace equipment.Hence, effective management of milling deformation of a thin-walled part will significantly improve its quality, which, however, is still made difficult by the lack of a real-time deformation perception, optimization, and control method. To bridge the gap, this paper proposes a novel online optimal control method of milling deformation for thin-walled parts by incorporating digital twins into the milling process of thin-walled parts. To this end, a reference framework of the milling process digital twin (MPDT) for thin-walled parts are designed, where the autonomous operation logic of MPDT for online optimal control of milling deformation is further clarified. On that basis, three key enabling technologies of MPDT are introduced from the perspective of multidimensional high-fidelity MPDT modeling, knowledge-driven lowlatency milling deformation simulation, and online optimal control of milling deformation, which provide an insight into the industrial implementation of MPDT. In addition, a MPDT prototype system is implemented, where its application and evaluation results demonstrate the feasibility and effectiveness of the proposed approach.

In the Industry 4.0 era, the Digital Twin has become one of the most promising enabling technologies supporting material flow. Although the literature on the Digital Twin is becoming relatively well explored, including a certain number of review papers, the context of the Digital Twins application in internal transport systems has not been investigated so far. This paper thoroughly reviews the research on the Digital Twins applied in internal transport systems concerning major research trends within this research area and identification of future research directions. It provides clarification of various definitions related to the Digital Twin concept, including misconceptions such as a digital shadow, a digital model, and a digital mirror. Additionally, the relationships between terms such as material handling, material flow, and intralogistics in the context of internal transport systems coupled with the Digital Twin are explained. This paper’s contribution to the current state of the art of the Digital Twins is three-fold: (1) recognition of the most influential and high-impact journals, papers, and researchers; (2) identification of the major research trends related to the Digital Twins applications in internal transport systems, and (3) presentation of future research agendas in investigating Digital Twins applied for internal transport systems.

Digital Twin is defined as a realistic digital model of an object's physical state, representing its interaction with the environment in the real world. The research on Digital Twin has been advancing intensively in recent years. As a result of an emerging and broad research topic, various interpretations and Digital Twin applications have been developed. In this scenario, there is an opportunity to research the Digital Twin types and understand the concept evolvement. This paper provides an overview of the Digital Twin concept, classifies the existing body of literature, and discusses the Digital Twin evolution. Therefore, this research applies a combination of methods, including bibliometrics, natural language processing, and content analysis. The results show an expansion of Digital Twin's role from an enabler of cyber-physical systems to a product lifecycle data integration and processing platform.
