![]() ![]() To ensure safety and stability, it is necessary to carry out real-time and accurate fault diagnosis of PMSM. Permanent magnet synchronous motors (PMSMs) have been gradually used as the driving equipment of coal mine belt conveyors. As the result of this case study, a 6.01% increase in the commercial production line efficiency and an 87.56% gain for downtime are achieved. This study is one of themost comprehensive studies in the literature related to automotive production therefore, it puts forth the power of using digital twin technology in that area. In this study, the use of digital twin technology in the commercial production phase of the automotive production line with a case study is introduced. This enables each phase of the development cycle to be simulated, processed, and validated to discover the potential problems before the production of real components. Furthermore, simultaneous data capturing from the sensors and data processing are also available in the digital twin. The product development, including its software, electronics, mechanics, and physical behavior, is included in the digital twin of the product. The manufacturing sector is one of the areas where the advantages of digital twin technology can benefit mostly. Experimental results have proven that the proposed CPMT Platform can significantly improve the overall production efficiency and effectiveness in the shop floor. Third, different applications are developed to demonstrate the advantages of the proposed CPMT Platform, including an OPC UA Client, an advanced AR-assisted wearable Human-Machine Interface and a conceptual framework for CPMT powered cloud manufacturing environment. An OPC UA-based CPMT prototype is developed and further integrated with a previously developed MTConnect-based CPMT to establish a common CPMT Platform. Second, to address the issue of interoperability between OPC UA and MTConnect, an MTConnect to OPC UA interface is developed to transform MTConnect information model and its data to their OPC UA counterparts. ![]() First, a development method for OPC UA-based CPMT is proposed based on a generic OPC UA information model for CNC machine tools. This paper proposes a CPMT Platform based on OPC UA and MTConnect that enables standardized, interoperable and efficient data communication among machine tools and various types of software applications. Development of CPMT requires standardized information modelling method and communication protocols for machine tools. Cyber-Physical Machine Tools (CPMT) represent a new generation of machine tools that are smarter, well connected, widely accessible, more adaptive and more autonomous. ![]()
