Abstract: For smart manufacturing production lines of precision parts with multiple brands and heterogeneous control systems, traditional modeling methods face challenges such as the separation of mechanical and electrical systems and system isolation. This paper proposes a digital twin-based virtual commissioning method, constructing a high-fidelity 3D production line model within the NX MCD platform. The method sequentially develops 3D geometric, physical behavior, process simulation, control logic, signal mapping, and simulation commissioning models. Using PLCSIM Advanced and OPC UA communication, it integrates heterogeneous control systems into a collaborative simulation environment that combines mechanics, electronics, and control. Research results show that this approach enables comprehensive verification and optimization of design, process flows, and control logic before physical construction. It allows early detection of design flaws and logical conflicts, shortening development cycles and reducing commissioning risks. The six-model integration method offers a viable technical pathway for virtual simulation and commissioning of production lines with heterogeneous equipment.
